I found a "T...y Louise" [Lue/Lou was a nickname) married to a James W. Vaughn on RootsWeb in a file by Bruce York.Shows her b. Mar 1864, TN and James b. 1858/9 TN.
Four children born from that marriage were Ulysses S. Grant b. 1877/8, Russell M. b. 1880/81, Yonny b. Feb 83 and Mattie L.Shows a child from a 2nd marriage...named Walter D. b. 1892.No name for second husband.
It does not show a last name.I have no Lou/Louise's in my Kinnaird database, but will check again for a "T" first name.Hope this helps.
