"Hardford Burass", his wife Margaret A, and his two daughters in the 1880 census:
"United States Census, 1880," database with images, FamilySearch(https://familysearch.org/ark:/61903/1:1:MC89-24J : accessed 5 April 2016), Hardford Burass, Hendren, Washington, Kentucky, United States; citing enumeration district ED 210, sheet 447C, NARA microfilm publication T9 (Washington D.C.: National Archives and Records Administration, n.d.), roll 0445; FHL microfilm 1,254,445.
Wouldn't Margaret have brought her daughters to a second marriage? Might be time to revisit this woman as the one who later married McRay. -NGP
