Well, looking through my Harrelson lines, I ran into this one with no indication that it had been reviewed and it needs attention or rather several profiles need your attention. First of all, I think that Find a Grave is wrong. I went to the DAR records and it looks like they have convoluted a Matthew Martin in Williamsburg County, SC with a Matthew Martin in Marion County, SC and thrown in parts of a Matthew Martin from the upstate in Pickens County who moved to Tennesse.
It may be that Susannah Harrelson is attached to the wrong Matthew Martin. I do not know. I do know that I followed the application of a relative of mine Kate Reaves Daniel and several others. It all leads to the same place. :-) Here are the profiles.
Matthew Martin, Sr.
Matthew Martin, Sr.
It is at the children level where things break down. I believe they are two separate people but have information that is maybe mixed up.
Any help appreciated.
