Individual Details

According to her father's obituary, Nellie married Oliver Curtis Martin. They were living in New York in March of 1933. George Findley suggests three children - Harmon, Payne, and Keith. He stated Nellie and Curtis Martin were married 25 Nov 1896, but Nellie was counted in the 1900 census at home with her parents as Nellie Harmon - the 1910 census states they had been married nine years - so this date is wrong.
