The 1819 tax list (from the reconstructed 1820 Census of the Territory of Arkansas) lists Elizabeth and Lawrence Bradley, which shold mean it shows Elizabeth as adm of Lawrence Bradley, it is just an every name index and doesn't include any other information. Their son George is listed as being taxed in Independence and Lawrence County.
Could they have had a daughter named Keziah? Keziah Bradley born in SC married Thomas Martin, they lived in Crawford, Lovely and Washington Counties before moving to TX. Joseph Martin father of Thomas Martin moved from Wilson County, TN to Lawrence County, AR and was in the area of Strawberry Township when he gave a deposition in a lawsuit in 1822, he was in Lawrence by 1820. The surname Bradley for Keziah comes from her sons death certificate in TX. Keziah and Thomas named a son William Lawrence Martin.
