"Other than being next door to William Callow, tailor, is there anything which makes James Corkill and Mary Callow's son James "fit" better? It would be good to find mariner James in a census after 1851 (died between 1867 and 1877). "
So, no, the "James son of James Corkill and Mary Callow" in my 9.52 am message is the wrong James, I think. Yours is much better.
Do you think that James was away at sea for the 1861 census, and may have managed to "slip through the net" (metaphorically speaking !)
I've been looking at a tree on Ancestry which has this family and follows James's brother, David b 1843, and his descendants. I haven't looked closely, but it seems that David married Mary Ann Kewish in 1865, emigrated to Illinois, and then when Mary Ann died in May 1884, he returned to the IOM to marry Catherine Sayle in 1885 and returned to the USA (Kansas) with her.
