One difficulty researching the Burts of Halifax County has been the occurrence of several William Burts in that location. Richard Burt and Rebecca Stephens had a son William whom we suspect was the William Burt Sr. of Halifax County who died in 1824. Another William Burt, whose wife was Elizabeth [-?-], died in 1804. Joseph Burt Sr. had a son named William Burt, possibly born about 1775 and alive in 1812, about whom we know nothing more.
The following William Burt could have possibly been that son of Joseph Burt Sr., or yet another William Burt. This William Burt lived in the town of Halifax.
