I reently posted a Query to the RootsWeb LONG Message Baord seeking additional information about William A. LONG.
William A. LONG is enumerated in the 1860, 1870 and 1880 Census residing in Ellis County, Texas, with his wife Nancy Jane (Roper) LONG and children. The birthplaces of the children suggest that William LONG settled in Texas in or before 1850.
