I would love to have any of the information you have on any of those three.
I have seen others that feel Dawson, Albert, and Henry were brothers and I pursued this avenue for a while. They are connected to the Jesse Holleman I mentioned in my post with reference to John F. Schunk's site, but I don't think they were brothers.
There is an Albert Holleman (1820-1864) son of Jeremiah (John,Jesse) Holleman. Albert was in Cumberland, VA in 1850.He ended up in Sevier AR on the 1860 census and then died before the next census. There is an Albert Holleman on the 1840 census in TN of the right age, but I suspect that is not the right person.
Dawson Holleman's lineage is not shown on John F. Schunk's site, but he is mentioned as a grandson in Jesse Holleman's 1823 will there. A Dawson Holleman was in Cumberland, NC, on the 1840 census and in 1860 there is a D.B. Holomon age 50 in Harnett NC which was formed from Cumberland.
