Grays of Louisiana in 1860
It stands to reason that if William consistently identified his birthplace as Louisiana and he was born on or before 1840, there must be some records of him in the 1850 or 1860 census.  This page is a record or census searches conducted over the years.  It includes only those Grays that had a recorded William or W. in the census.
