I realize this is an old thread. I hope people are still following it...
I'm descended from T.V. Barnard's sister Stella.
Theridas Vera Barnard was born 10 SEPT 1873, in Patrick County, VA. I've got the same date as you for his marriage to Ada Moore.
1900 Census lists him in Hendricks, Indiana with wife Ada and daughters Venice and Laura.
1930 census lists him in Omaha with wife Ada, married daughter Mabel, son-in-law Oliver Wolcott, granddaughter Annabelle Lee Wolcott, and son Woodrow.
I have some pictures from a Barnard family reunion. They're dated 1963, but the reunion must actually have taken place a few years before that, as some of the people in the pictures died before 1963.
They won't let me post links on this board, but a google search for Theridas Vera Barnard should bring up my site, garthhagerman dot com.
