2. A marquess, marchio, is the next degree of nobility. His office formerly was (for dignity and duty were never separated by our ancestors) to guard the frontiers and limits of the kingdom; which were called the marches, from the teutonic word, marche, a limit: as, in particular, were the marches of Wales and Scotland, while they continued to be enemies countries. The persons who had command there, were called lords marchers, or marquesses; whose authority was abolished by statute 27 Hen. VIII. c. 27: though the title had long before been made a mere ensign of honour; Robert Vere, earl of Oxford, being created marquess of Dublin, by Richard II in the eighth year of his reign[f].

3. An earl is a title of nobility so antient, that it's original cannot clearly be traced out. Thus much seems tolerably certain: that among the Saxons they were called ealdormen, quasi elder men, signifying the same as senior or senator among the Romans; and also schiremen, because they had each of them the civil government of a several division or shire. On the irruption of the Danes, they changed the name to eorles, which, according to Camden[g], signified the same in their language. In Latin they are called comites (a title first used in the empire) from being the king's attendants; "a societate nomen sumpserunt, reges enim tales sibi associant[h]." After the Norman conquest they were for some time called counts, or countees, from the French; but they did not long retain that name themselves, though their shires are from thence called counties to this day. It is now become a mere title, they having nothing to do with the government of the county; which, as has been more than once observed, is now entirely devolved on the sheriff, the earl's deputy, or vice-comes. In all writs, and commissions, and other formal instruments, the king, when he mentions any peer of the degree of an earl, always stiles him "trusty and well beloved cousin:" an appellation as antient as the reign of Henry IV; who being either by his wife, his mother, or his sisters, actually related or allied to every earl in the kingdom, artfully and constantly acknowleged that connexion in all his letters and other public acts; from whence the usage has descended to his successors, though the reason has long ago failed.

4. The name of vice-comes or viscount was afterwards made use of as an arbitrary title of honour, without any shadow of office pertaining to it, by Henry the sixth; when in the eighteenth year of his reign, he created John Beaumont a peer, by the name of viscount Beaumont, which was the first instance of the kind[].

5. A baron's is the most general and universal title of nobility; for originally every one of the peers of superior rank had also a barony annexed to his other titles[k]. But it hath sometimes happened that, when an antient baron hath been raised to a new degree of peerage, in the course of a few generations the two titles have descended differently; one perhaps to the male descendants, the other to the heirs general; whereby the earldom or other superior title hath subsisted without a barony: and there are also modern instances where earls and viscounts have been created without annexing a barony to their other honours: so that now the rule does not hold universally, that all peers are barons. The original and antiquity of baronies has occasioned great enquiries among our English antiquarians. The most probable opinion seems to be, that they were the same with our present lords of manors; to which the name of court baron, (which is the lord's court, and incident to every manor) gives some countenance. It may be collected from king John's magna carta[l], that originally all lords of manors, or barons, that held of the king in capite, had seats in the great council or parliament, till about the reign of that prince the conflux of them became so large and troublesome, that the king was obliged to divide them, and summon only the greater barons in person; leaving the small ones to be summoned by the sheriff, and (as it is said) to sit by representation in another house; which gave rise to the separation of the two houses of parliament[m]. By degrees the title came to be confined to the greater barons, or lords of parliament only; and there were no other barons among the peerage but such as were summoned by writ, in respect of the tenure of their lands or baronies, till Richard the second first made it a mere title of honor, by conferring it on divers persons by his letters patent[n].
