DNA of Perrott ap Rice 1600

Descendant's of Perrott and his children: Perrott jr,Edward, Thomas should be tracked down to see if we can get a live swab for comparrison to Samuel/John Rice of Dedham. A positive correlation with John and Samuel would indicate that Perrott is the FATHER of John Rice 1624 of Dedham....I expect mine to be a matach but we need a match from other sons of Perrott. ANyone out there know if H.Ross Perrott connects to Perrott ap Rice 1600 of Tenby?
