I have a Mabel CASS, but her given name might have been Isabella.My grandfather's aunt was Mary Ann BUTLER CASS (b abt 1861 Ireland d 1909 Chicago.)Her husband was William H. CASS (b abt 1832 ME d 1902 Chicago.)The 1900 census says Mary Ann had one child, Isabella b 1881 and living with them.Mary Ann's obit names her daughter as Mrs. Mabel WYKOFF (not Isabella) of New Carlisle IN.In 1925 a Mrs. M. WYKOFF signed the death certificate of Mary Ann's sister, Belle BUTLER RUSS.At that time Mrs. M. WYKOFF was living in Chicago on North Clarendon.Belle was married abt 1895 to Ode RUSS and it was her second marriage.Might have been married to a McMULLAN or McMILLAN first, or maybe a George HOOPES.Belle's given name might have been Elizabeth (1870 census.)Anyway, in 1900 the CASS family (William H., Mary Ann and "Isabella") were living at 3144 Armour Ave in Chicago.Also at the same address:Walter C. TUCKER b 1853 ME, with daughter Jessie b 1883 IL, son Herbert b 1878 IL andmother-in-law Charlotte BUTLER b 1841 Ireland."Charlotte" I believe to really be Catherine, mother of Mary Ann BUTLER CASS. If any of these people sound familiar, I'd be happy to know.
