Sir George was born in Mayfair, educated at Charterhouse, and appointed to a clerkship in the Colonial Office in 1825.
In the same month he was appointed secretary to the Order of St. Michael and St. George, a post he held concurrently with that of chief clerk in the Colonial Office, until his retirement in September, 1872.
[3] He was succeeded in the baronetcy by his eldest son, John Croker Barrow, author of the Valley of Tears and other poems, in which there are some in memoriam verses to his father.
In early life Sir George too exhibited poetic taste in a translation of some odes of Anacreon, which was spoken of favourably by William Gifford, first editor of the Quarterly Review.
In 1850, Sir George laid the foundation-stone of the Barrow monument erected to his father's memory on the Hill of Hoad, Ulverston.
