I am not the most knowledgeable of the Mountcastle line but am trying to compile the information of a family member in Richmond Virginia. As he doesn't have a computer and enternet service, It will be spring before I can put most of the info on Computer. At present I have only two Henry Mountcastle's and do not have a wife or children for them. the first Henry is the son of Joseph Joab Mountcastle, and died September 25, 1770. The second Henry, I have as the son of Joseph and Elizabeth and the Uncle of the first. I do not have parents of Joseph and Elizabeth. Please e-mail to exchange info.
