Looking for any information on Erastus M. Birch, who married my widowed great-great grandmother Sarah Ann Ellis (Shoup)in Greene County in 1866. Is this the same Erastus Mitchell Birch (1801-1886) who was married to Sally Milligan in 1830 in Massachusetts and was the father of Hugh Taylor Birch? He would have been 65 at the time of the marriage, and fathered two children in 1868 and 1870. Or, may this have been his son (I don't know that he had one by that name). Sarah Ellis is listed in Cook County, Illinois in the 1880 census as Sarah Shoup. Family tradition said that her son Alonzo David Birch "assumed the name Shoup early in life". Does anyone know why? Any help would be greatly appreciated.
