The marriage for Lindsey to Judith was found in "Lancaster Co. Marriage bonds 1652-1850" compiled by Ida J. Lee, 1972. I didn't pursued the Dameron family so I can't say who she was related to or how.It's been quite a while since I've looked at any of my records on the Lancaster Pullens.Everything is in paper files for them because my database crashed and I never fully reconstructed that line back into the database.I became somewhat convinced we didn't descend from that line and started looking at other lines. As for the Lindsey being in the RW, I think I found that in a book or CD that listed VA soldiers.I know I saw his name on a list of soliders.I'll have to double check my sources to nail down which source.
You might take a look at Thaddeas Pullen of Lancaster.He seems to be a bit older than Lindsey and married twice in the 1790s in Lancaster Co.I had speculated he & Lindsey were most likely related and I've never been able to connect him to any particular family line.
As for the DNA, I think there may be a sample for the Lancaster line but is not noted as such.Some other ancestor is posted but, if memory serves, that ancestor descended from the Lancaster line.Tim Pullin is in charge of the DNA page.You might possibly e-mail him and ask if he knows.
