I'm searching for more information on Samuel BLAIR and family members of Blair Valley, Washington County. Information found indicates that Samuel was born about 1792, a son of John BLAIR and Frances/Fannie ? (possibly Mills). Samuel married Mary Ann ? and had at least two children, Samuel Andrew, who used the name "Andrew" and a daughter, Sarah. I have an Andrew BLAIR born about 1810 - 1815 who had a sister Sarah born abt. 1815 and I am wondering if these might be the same people. The first record I found for my Andrew BLAIR was on the 1850 Census when he and his family are listed in Conemaugh Township, (Johnstown) Cambria County, PA. His sister, Sarah, is recorded on the 1850 Census for Bedford Township, Bedford County, PA. I have no information on their parents. Andrew married Susannah/Susan ? approx. 1845 as his first child is recorded as being born 1846. This would make him approx. 35 to 40 years old, so perhaps this is a second marriage. Gratefully appreciate any input. Barb CA
