E-MAIL MESSAGE OF DIARMID CAMPBELL RE ANCESTORS OF JOHN CAMPBELL
Date:01 January 199

" ...although a number of people have attempted research in Ireland absolutely no further information has appeared about the ancestry of Duncan Campbell who married Mary McCoy.

"Pilcher states quite clearly at one point in her book that her information on those earlier (likely fictitious generations going back to Inverary) were taken by her from an elderly relation who thought she remembered that information.Pilcher had not intended to publish her book and it might have been better had she not, since the misinformation has misled so many and God knows how many family histories have now been published giving her bogus material as their source.Her later material appears to be more sound, although since she often gives no sources or references (as to where material was found), it means that anyone of the descents of those whom she outlines has to re-do the research.

"I have also thought that there might be some connection between the Drumaboden and the 18th century Virginia Campbells.But none has as yet appeared.Two professional research efforts in Ireland have so far been conducted, one just completed and the other in the '80s.These were conducted by getting a group of descendants to put up some funds each and were co-ordinated through the Genealogists of the Clan Campbell Society of the time.While both were helpful in clarifying where no information could be found (so making easier any future research efforts), neither produced any clarification on the ancestry of either family going back from Ireland to Scotland.

"If you want the results of the second research effort you could write to the Society Genealogist, Dr.Ruby G. Campbell PhD, 3310 Fairway Drive, Baton Rouge LA 70809 USA, and ask her to let you know what to send her for the photocopying and mailing costs.But the information is not, I seem to remember, directly concerned with Drumaboden. ...

" ... There are in fact three sets of Northern Irish Campbells who may or may not be connected: Drumaboden, Duncan and his cousin Dugald Campbell, and the 18th century Virginia Campbells descended from one John Campbell who came over to Pennsylvania at a fairly advanced age in the 1720s or 30s."

Disconnecting him as son of Andrew Dugan Campbell
