There is a privately published, 500 page “book” titled "The Family of John Kincaid, Sr. (1710-1811), and Kincaids of the Carolinas and Virginia with Expanded Research in Burke and Caldwell Counties, North Carolina”. I have used this book extensively for my Kincaid family tree research (John was my 4th great grandfather). The book has some information on Rev. W.W. Todd and Sophia Kincaid. This is contained in a note at the end of the section on the descendants of Milton Wilburn Kincaid. I will repeat the information below (as close as possible to what is in the book):
NOTE: some information on Sophia Rebecca Todd Kincaid, second wife of Milton Wilburn Kincaid. Sophia’s maiden name was Moore.
At the time of her marriage to Milton, Sophia was the widow of Rev. W.W. Todd b. June 26, 1819 d. Jan.15, 1854. Rev. Todd was a Methodist Minister, he is buried in Fairfield Cemetery. Sophia was 45 years old when Milton Kincaid died, she did not remarry.
Sophia had 4 children by Rev. W.W. Todd:
(1) William A. Todd b. May 3, 1833 d. July 25, 1862, he did not marry, unable to get further information.
(2) James L. Todd, went to McKinney, Texas to live.
(3) Charles S. Todd married Rebecca Elizabeth Kincaid, daughter of Col. John Kincaid.
(4) Mary Ann Todd married Lambert Augustus Bristol.
From the above information, you can see that James had a Kincaid sister-in-law, married to his brother Charles. They were married in 1868. Additionally, I have his full name as James Leroy Todd. I have extensive notations on my sources but unfortunately not for where I got the “Leroy”.
From other information I have, James had Kincaid half-siblings born to Sophia and Milton Wilburn Kincaid. These were (1) Finley Milton Kincaid, Sr., (2) Sarah Catherine Kincaid, (3) Luticia Rebecca Kincaid, and (4) Alonzo A. Kincaid.
