Was with parents and six siblings (and Uncle Alexander Gibson and two non-relatives) in 1850 (aged "13"). FamilySearch transcribed the parents' surname as ""Leoan" and the children's as "Sloan".
Not there at the 1860 census - maybe in Maryland about to meet Sarah?
By 1870, he was a householder-farmer with $12,000 real estate right next to his parents' house, presumably the same one, in Ross Township, Allegheny County, Pennsylvania; FamilySearch transcribes surnames in his household as "Sevan". Nellie was 8 months old.
