The two Bird/Byrd lines I have is Nathaniel that married Mary Lea they lived in Dist 9 Solway. The other family is John that married Tabitha Dunn they lived off Emory Rd in Beaver Ridge Dist 19. They owned a dary and ran a store in later years.

I do not know if the two families connect or just share a common surname. As to the families moving to MO probably correct though I have not tried to follow all the children. Several families left for MO during the 1830 then again after 1850 to MO and TX.

Any help would be great Barbara
