Hi Pat, On Silas Hilliard-go to website LaMartin.com and look under their Underhill file. Punch in Kyle Vanlandingham into Google and you should get a lot of his Hilliard/Underhill info. He probably knows as much about these families as anyone. I have seen where he says he's has researched them for over 30 years. I have a copy of Kyle's book "Florida Cousins-The Descendants of William H. Willingham" and lot's of Hilliard info if I could be of help. Silas was my GGG Grandfather. --
