Dr. Romanes was descended from an old Scottish family settled since 1586 in Berwickshire: he had been educated at the High School and University of Edinburgh, and was an excellent classic and learned theologian, with views of a strictly 'Moderate' type. From him his distinguished son inherited the sweetness of temper and calmness of manner which characterised George John Romanes through life, and which earned for him amongst his friends the playful sobriquet of 'The Philosopher.'

Dr. Romanes married, after his arrival in Canada, Miss Isabella Gair Smith, daughter of the Rev. Robert Smith, for many years parish minister of Cromarty. Mrs. Romanes was connected with several old Highland families, and was a thorough Highlander. Handsome, vivacious, unconventional, and clever, she was in all respects a great contrast to her husband, who, as years went on, seems to have lived mainly the life of a student, and to have left the care of mundane things to his wife. Three sons and two daughters were born. Of these, only two, the eldest son and youngest daughter, now survive.

In 1848, the inheritance of a considerable fortune relieved Dr. Romanes from any necessity to continue the duties of his chair, and the family returned home, wandering about for a few years and finally settling in 18 Cornwall Terrace, Regent's Park. There was a good deal of continental travel during these first years after their return, and as he grew into boyhood George Romanes spent several months at various times in Heidelberg and other German towns, and the family performed a journey from Nice to Florence in a delightful and now bygone fashion, travelling with a vetturino.

Probably the beauty of the scenery, the fascination of travel, and the charm of the beautiful surroundings exercised an unconscious influence over the boy, and did something to rouse the poetic sense which was to be so great an element in his life. Otherwise there seems to have been little or no sense of pleasure in the art treasures or the historic associations of Italy, and at no time of his life did he ever care for pictures in anything like the same degree as he loved poetry or music.

After the family settled in London, George Romanes was sent to a preparatory school near his own home. Two of his schoolfellows became in after life intimate friends. These were Francis Paget, the present Dean of Christ Church, and his brother, Henry Luke Paget, now Vicar of St. Pancras, London.

An attack of measles put a stop once and for all to his preparatory school career, and the idea of a public school was never entertained.

He was educated in a desultory and aimless fashion at home, and was regarded by his family as a shocking dunce. Parts of two years were spent in Heidelberg, and here he picked up some German, and had a few lessons on the violin, and saw as he grew up something of student life in Germany. Music was always a perfect passion with George Romanes, and if a little wholesome discipline had been exercised, the boy might have become a very good musician.

Heidelberg and the days at Heidelberg represented to the younger Romanes the 'golden age.'

They lived in an old house outside the town, surrounded by woods, and here the children, George and his younger sister, roamed about to their hearts' content, making collections and keeping pets, like the born naturalists they were. Shockingly idle children but marvellously happy ones, and in the peculiar 'let alone' system of their household, they grew up, neither of them remembering any reproof, far less any punishment, nor any attempt to make them learn lessons or carry on studies for which they were not inclined. A long interval of years separated the brothers, now only two in number,[1] and the younger brother and sister were looked on and treated as children long after they had emerged from childhood.

The father and mother seem to have attended Presbyterian and Anglican churches with entire impartiality, but the younger members of the family preferred the English church, and were confirmed in it. Religion was a potent influence with the boy in quite early years, and there grew up in him a purpose of taking Holy Orders, a purpose which met with no encouragement from either of his parents.
