Hi Jennifer, just wondering if you ever found the family of Martha Louise. She can be seen in the 1870 and 1880 census of Hannibal, Oswego Co., NY. Her parents are George W. DANN, born about 1832 in Oneida Co., NY, and his wife Ruth, born 8 Jan 1838 probably of Hannibal. Martha L. had as many as 7 siblings. Her father George W. is the son of Ezra and Sarah C.DANN, both born in Rensselaer Co., NY. And then I believe Ezra, born about 1801, is the son of Thaddeus and Sarah DANN. Thaddeus was born 17 Jul 1772 in Stamford, Fairfield Co., CT. I'm trying to determine who the wife of Thaddeus is. I'm leaving another message regarding that couple.
