Arnold, thanks for the informative response. My line is through a daughter of Willam Preston and Susannah, Polly P. Preston who married Benoney Overstreet in 1825. Aside from my direct line(Overstreet/Roach) this is all I have on the Preston or Abston families. Much work to be done. Incidentally somewhere not long ago I came across an 18th century Abston document from Prince Georges Co.,MD but right now I can't recall where it was that I came across it. I though it possible that there may be some connection to my Abston line but not knowing that I didn't copy it. I will find itagain and relay the same when I do. Thanks again.
