I, too, am trying to track down information on Jane who was married to John Turnbull. From what I can piece together, John lived with his Aunt Isabella Clague in 1851 (if Jane was Jane Clague, assume that she was related to Isabella Clague?). Jane and John were married and then lived in Liverpool in 1861 with their children Margaret Ann (6) and Catherine Jane (3mo) and a visitor Ann Cubbon. (If Jane was Jane Cubbon, I assume that Ann was one of her relatives?). By 1871, both John and Catherine had died and Jane was a widow living with her daughters Margaret Ann (now 16) and Isabella (4). By 1881, Jane and Isabella were living with Margaret Ann and her husband George Crebbin in Liverpool. Margaret and George were my mother's grandparents.
Any information you can provide on whether Jane was Jane Clague or Jane Cubbon would be greatly appreciated!
