Which Isaac Huckabee and which Berryman Huckabee are you talking about? There was an Issac Cal Huckabee son of Berryman & Elizabeth Huckabee and there was an Issac B Huckabee who was brother to Berryman William Huckabee. Issac B & Berryman William were sons of William M Huckabee & Nancy Williams.Issac Cal & William M were brothers.Both Issacs are buried in Arkansas.Issac Cal is buried in the Huckabee Cemetery in Hope, AR. As far as a Thomas connection there are several Thomas Huckabees but they are not in our direct line.If you are referring to an older Thomas connection there is some belief that Thomas Huckabee was Joshua Huckabee's father and that Joshua Huckabee might be Berryman's father. Joshua had 8 children (4 boys & 4 girls). I know that two of those sons were John & Joseph. Although early records show Berryman in the same area and church it has not been proven that Joshua is his father.
