I am looking to find the maiden names of the 2 wives of my great-grandfathers' brother Joseph T(homas) Jones. Their first names were Carrie and Ada.
I can find Carrie listed on the 1910 census with Joseph and children, but nothing after that. I find Ada listed on the 1930 census with Joseph with no children; all having lived in the city of Danville.

I can't find the marriage records due to the lack of maiden names of these women. If anyone can help me fill in some blanks of my family I will appreciate it.

Papemortuary.com has obits of people who died in Vermilion County. There is Joseph T. & Carrie listed.
the Iliana Genealogical & Historical Society of Danville has marriage records form 1827 to 1915. The marriage record for Ada & Joseph would give you parents name. The Marriage record would cost you $3.00 plus mailing cost. Check it out
