Hello Stephani, welcome to the Titus Clan. He's my gg grandfather too. William Haizelet Titus was my grandfather and Earl Wesley Titus was my dad. I can give you some information on that line but mines still a work in progress as I make sure I can verify numeriously what I put in my tree. There are other reliable trees that I can also point you toward.
We have as far back as David but want to go back past him, thats where we got stuck also. But hints come in and several of us will check that out before we add it to our tree.
My tree is Titus, Jameson, Fischer,Estrada,Wotring, Krause. I know I got carried away. New England Ball Project is another tree that has alot of info as well, you might take a look at it too.
When we figure it out I'll repost the info
