My ggg-grandmother was Catherine/Katherine Siebert, she was possibly born in Ohio or Germany about 1830. She died in Galveston, Texas 2 Jan 1866 in childbirth. She was married to George W Thomas on 13 April 1855 also in Galveston. She was the mother of four daughters, the youngest my gg-grandmother Katherine Louise. The other daughters were: Caroline, Anne Augusta and Elizabeth. I have no other information on Catherine, and would appreciate any help.
