Fenwick's career was in the first instance suggested by some incidents in the life of the painter George Romney. Romney, as is well known, married a Kendal girl in his early youth, and left her behind him in the North, while he went to seek training and fortune in London. There he fell under other influences, and finally under the fascinations of Lady Hamilton, and it was not till years later that he returned to Westmoreland and his deserted wife to die.
