I have Frederick James Hancox in my tree but born December quarter 1865 with father James (1831-1915?) and mother Sarah Ann (c1836-c1868). I also have him marrying Piety Woodfield in 1906 but don't think she was a widow. She seems to have been born 1867 in Tysoe under that name. Their 2 children were already in their teens when Frederick & Piety got married. Thought this might be of interest. Incidentally I don't know when either of them died, do you have any dates? Also do you have more details of your great grandmother Dinah and her branch of the Hancox tree please?
