Sir William Fraser[16] in a note to the Sutherland Book—a mere obiter dictum, however—doubts Skene's suggestions "that Johanna, Lady of Strathnaver, who married Freskin de Moravia, Lord of Duffus, about 1240, was the daughter of John Haraldson," that is Earl John, and that "Magnus of Angus was the son of a sister of a former Earl of Caithness," and states that "Skene's arguments are plausible, but there is no very good evidence in support of them." Skene's argument rests mainly on the names "Johanna" and "Magnus," by itself an insecure foundation, and one which it is hoped to explain or remove, adopting the argument from "Magnus," a name which constantly recurs, and rejecting the argument from "Johanna," a name which never again appears, in this family.

A century or more after the death in 1231 of Earl John, we find Reginald Chen III, known as Morar na Shein or "Lord" Schen, in possession of a moiety of the Caithness earldom, without the title, and living in Latheron and Halkirk parishes, while the other moiety was held by the Caithness Earls of the line of Angus, and in 1340 we find Reginald More, Chamberlain of Scotland, ancestor of the Crichton or Sinclair Earls of Caithness, acquiring from Malise II, one of the Stratherne Earls of Caithness and a descendant of the line of Paul and also of the line of Erlend, part of south Caithness (including Berridale), which therefore Reginald Chen III did not then own or acquire, though he owned half Caithness. But Reginald Chen III did acquire Berridale and other lands later in David II's reign according to Origines Parochiales, II, p. 764.

Now it is known from other sources that Reginald Chen III was a grandson of Johanna of Strathnaver, the mysterious lady of unrecorded parentage already referred to, who owned land in "Strathnauir," and who was dead in 1269, and who had married, at a date which we hope to fix, Freskin de Moravia, Lord of Duffus, then also dead, and had had by him two daughters, Mary and Christian, who were married respectively to Reginald Chen II and William de Federeth I (whose sons respectively were Reginald Chen III and William de Federeth II) and these ladies succeeded each to one fourth of Caithness; and a grant,[17] which was made in David II's time by William de Federeth II in favour of Reginald Chen III, placed him in possession of William de Federeth II's quarter of Caithness. Reginald Chen III thus had all the half share of Caithness which was held by his grandmother, Johanna of Strathnaver. We also know that by another grant in 1286[18] William de Federeth I had already conveyed to Reginald Chen II four davachs of land in Strathnaver and all his other lands there; and, besides these grants, we have authentic record in May 1269, which recites that Lady Johanna had before that date granted a considerable part of her lands in Strathnaver to the Bishop of Moray for the maintenance of two chaplains to minister in the Cathedral of Elgin.

By the above record, which is a regrant of the Strathnaver lands by Archebald Bishop of Moray in May 1269 to Reginald Chen II, not only is his marriage before that date to Mary daughter of Johanna by Freskin de Moravia proved, but the lands in Strathnaver are identifiable. They were "Langeval and Rossewal, tofftys de Dovyr, Achenedess, Clibr', Ardovyr and Cornefern," which now are known in part as Langdale, Rossal, Achness, Clibreck and Coire-na-fearn, while "tofftys" are "tofts," and "Dovyr" and "Ardovyr" are respectively old Gaelic for "water" and for "upper water." "Dovyr" would denote the River Naver and loch of that name, and "Ardovyr" would mean Loch Coire and the Mallard River, that is the "Abhain 'a Mhail Aird" of the Ordnance Map (whatever that may mean),[19] which rises in Loch Coire, and, after a course of six miles from its upper valley, falls about 330 feet below its source into the River Naver at Dalharrold. These lands of the Lady Johanna lay partly to the south of Loch Naver, extended southwards nearly to Ben Armine, and stretched westwards to Loch Vellich or Bealach and the Crask and Mudale, eastwards to Loch Truderscaig, and northwards down the valley of the Naver at least as far as Syre. Part of them, close to Achness,[20] is to this day known locally as Kerrow-na-Shein, or Chen's Quarter, either after Johanna's son-in-law, Sir Reginald Chen II, or after her grandson of the same name, the great "Morar na Shein," about whom so many legends still survive in Cat. These lands in Strathnaver are roughly hatched on the map of Cat in this volume, and, as she gave them away in charitable trust, they probably formed only a small part of her whole estate after her marriage with Freskin de Moravia, which probably comprised the old Parish of Farr, now divided into Tongue, Farr, and Reay.

It is suggested that the ownership of these lands in Strathnaver and of the other upland territories in Halkirk and Latheron parishes, held by her descendants and sequels in all her estate, the Chens, connects the Lady Johanna with the family of Moddan "in dale" in Caithness and with Earl Ottar, and with Frakark and Audhild her niece, and that Johanna was entitled to these lands in their entirety in her own right as the sole descendant remaining in Scotland after 1232 of Harald Ungi's younger surviving sister Ragnhild, possibly through her son Snaekoll by Gunni, and that Snaekoll was next heir to these lands before he went abroad, and either that he was Johanna's father, or that she became Ragnhild's heir in his place. In this way Johanna would have a good right, especially if Magnus, son of Gilchrist, had been compensated for his mother's share by receiving a grant of South Caithness and its earldom, to receive a grant of the rest of the Harald Ungi half share of the Caithness earldom, lands previously held by Jarls and Earls St. Magnus and Erlend Thorfinn's son or some lands of equal value, and the reason why she had such very large estates as those which she brought to her husband and the Chen family as their successors would be made clear. For she would have completed her title to a large share of the Erlend lands, and also to the Moddan lands which Gunni and Ragnhild had entered upon and held after the elder sister of Ragnhild had left Caithness on her marriage with Gilchrist Earl of Angus.

In support of Johanna's title it is to be observed that neither Magnus II, nor his wife, is recorded to have claimed any part of the Strathnaver lands, a fact which indicates that Johanna and her predecessors had acquired an independent title to them, and that, too, a title not derived through Earl John. Again, (though in a time when records fail us, the argument proves little) Johanna, although from her probable date she might have been so, is not recorded to have been a daughter of John. Further, to be of suitable age[21] to marry Freskin she must have been born long after any known child of Earl John, even his son Harald who had died in 1226. Lastly, neither Johanna nor her husband Freskin nor any descendant of hers ever claimed either the whole of or any share in the Orkney jarldom,[22] which Earls Harald Maddadson, David and John had held in its entirety, and to which Johanna, had she been Earl John's only daughter, or her husband Freskin would have been entitled to claim to succeed as sole heir; while if John had had two daughters, and Johanna had been one of them, she or her husband Freskin would have been entitled to claim a grant of some share at least of the lands appertaining to the Orkney jarldom.

It was, however, Earl Magnus who made such claims, and with success, and he may well have obtained the Orkney jarldom and lands, and part of the Caithness earldom as well, with the title, not only as being the son of the elder of Harald Ungi's sisters, but as the husband of Earl John's nameless daughter, while his name of Magnus, afterwards so often repeated in the Angus line, came into that line obviously through his mother at his baptism, and not through his wife at his marriage.

The name of Johanna, on which Skene mainly founds his assertion that Johanna of Strathnaver was Earl John's daughter, is just as easily explicable, and with equal verisimilitude, if she was not. Snaekoll went to Norway in 1232, leaving behind him, on our hypothesis, one child, an infant daughter of tender years, or possibly as yet unborn. The child of a younger child of Ragnhild would probably be still younger. Heiress to very large landed estates and justly entitled to claim a moiety of the Erlend Thorfinnson half of Caithness and all the Moddan territories, this child would be made by the king of Scotland a ward, to be married, if female, in due course to a suitable husband. The Queen of Scotland, who in 1232 had been childless for eleven years and never had any children afterwards, was an English princess who was married to Alexander II on 19th June 1221, and lived till 4th March 1237-8, a period which would cover all Johanna's early years. The queen's name was Joanna, and Johanna of Strathnaver may have been called after her, as Earl John had possibly been called after her father King John of England, the friend of Earl John's father, Harold Maddadson.

We now have to fix the date of Freskin de Moravia, nephew of William, dominus Sutherlandiae since about 1214. Freskin, as stated, was undoubtedly the husband of Johanna of Strathnaver, and became on his marriage owner of her lands there as well as of a moiety of the Caithness earldom lands.

Freskin was, as also stated, the eldest son of Walter de Moravia of Duffus, second son of Hugo Freskyn of Strabrock, Duffus and Sutherland by Walter's marriage with Euphamia, probably, from her name, a daughter of Ferchar Mac-in-tagart, who became Earl of Ross.[23] As Ferchar granted[24] certain lands at Clon in Ross about the year 1224 to Freskin's father Walter de Moravia of Duffus without pecuniary or other valuable consideration, it has been concluded, probably correctly, that this grant was made on the occasion of the marriage of Walter to Ferchar's daughter Euphamia; and Freskin, their heir, was born in or after 1225, and had become dominus de Duffus by 1248 on his father's death. Johanna, on our hypothesis, would have to be born by 1232 at latest, that is, before or soon after her supposed father Snaekoll went to Norway, and from her supposed father's date she could hardly have been born before 1225. Snaekoll's date can be ascertained with comparative accuracy. For his mother lost her first husband, Lifolf Baldpate, only in 1198, at the battle of Clairdon, and she can hardly have married Snaekoll's father, Gunni, much before 1200. From these dates Snaekoll could have been born by 1201, and married in Scotland between 1224 and 1231, and Freskin and Johanna would thus be of very suitable ages to marry each other, and their marriage therefore would take place after 1245, or possibly as late as 1250. If Johanna was the daughter of a younger child of Ragnhild, she might be born later than 1225.
