This Margaret at age 23 in 1850 Says she was born in TN putting her born abt 1827, In 1827 When William Husband of Mary Berry died.. She could have been born in 1827.I would have to guess that she was born in AR. Also in William of Davidson Co Will, The other Grandchild named Was Gabriel Margaret Matlock who is married to Alex Buchanan had a son Gabriel. I assume that This Gabriel is named after her Brother??? For I doubt that Gabriel was her father
