Lucy Bryant/Briant is my ancestor through her son John, his son Zechariah, his son David, his son Zechariah R (ZR, his daughter Edith (my great-grandmother) Bryant Barger, their daughter Lucille Barger Butler, and her son Fred Butler, my father.
Monuments to Lucy and her grandchildren have been erected at the Poplar Springs Baptist Church Cemetery near Bradford in Gibson County.
David Briant is buried in the Bryant cemetery inside the Milan Arsenal, as is his father Zacharia and one of his wives Elizabeth (we don't know which Elizabeth)
She died in 1848 in Gibson County but here burial place is unknown. Her husband, Chunawee Bryant, was killed in the battle of Horseshoe Bend.
