In 1870, George Logan, age 22, stone cutter, is living with father Daniel age 65, and sister Mary Logan age 29, in Greenburgh, Westchester, New York. George married abt 1873 (don't have marriage record but daughter Eliza born Aug 17, 1873 in New Jersey) and Mary married abt 1875 to Henry James Kerwin (don't have marriage record). In 1875, in Brooklyn, Elizabeth's husband is George J. Logan, age 27, a stone cutter, so born abt.1848, daughter Eliza age 1. In 1880, in Village of Tarrytown,New York, Elizabeth's husband is George, age 29, stone cutter so born abt 1849. Also, sister in law Jeanette Johnston. Can't refind in 1900. In 1910, Elizabeth is living with her son-in-law James Wilson, is married, M1, has been married 36 years, has had 6 children, 6 still living (think only 3 are living). So Elizabeth always says married up to 1910 but where is George?
I paid for George's birth record on Scotland's People. There is a son George, no initial, born Aug 31, 1848 to Daniel Logan, laborer, and Mary Anderson.
So far, I am thinking that findagrave has the wrong date of birth for George A. Logan who died in 1908.On the 1880 census, George A. is 30 in Albany where he seems to have stayed. If George A. is in Albany in 1880, and our George is in Tarrytown, they have to be two different people. George A. had a daughter Jane, Christening: 17 Jun 1877, State Street Presbyterian Church, Albany, Albany, New York. the 1900 census says George in Albany born Aug 1846. the 1905 census says George in Albany age 55 so born 1850. which agrees with the 1880 census. I guess a death certificate might have his parents names.
