Lavinia Coffey Logan married Henry Snaden March 11, 1879. She is listed on the 1870 Tehama County Censis with her first husband, Green Berry Logan. She isn't found again until the 1900 Red Bluff, Tehama County Census. She is listed again in 1910 and 1920. Neither she, her husband Henry Snaden, nor her daughter, Nellie Logan, is found on an 1880 Census. It could be that they weren't at home during the time the census was taken or their name is spelled in such a way that I can't find it.
