Sorry, I don't have an Alvis or Sterling. I do have 2 Martha's: Martha "Mattie" b.1849 in Coffee Co., TN and Martha J. daughter of William Edward and Margaret M. Carroll.
These may be one and the same person because I have a DOB on one and no parents and vice versa on the other.
I have a James Gwin b.7/13/1834 Bedford Co., TN mar. 7/13/1853 Eliz. Cross in Coffee Co., TN and died 2/22/1892 Coffee Co., TN (parents John Milton Carroll and Martha Haggard)
I also have a James Richard b.6/21/1876 Coffee Co., TN mar. 1/31/1894 Jennie Robertson in Coffee Co., TN and died 12/4/1946 in Coffee Co., TN (parents Samuel Wilson Carroll and Mary A. Ward)
Hope this helps, let me know if you connect.
