Thanks for responding, John.  Actually, I thought Jackie Healy-Rae's line came from a Daniel Sullivan marrying a Mary Sullivan McCann.  My cousin Peggy O'Sullivan Blake is the person I have been in touch with...I think she's actually in Beaufort or Fussa/Fossa...not sure which, but close enough.  She is related to the Healy-Rae's through marriage for certain...I think her father, Cornelius O'Sullivan, was the brother of Bridget Sullivan, one of Jackie Healy-Rae's father's two wives.  She may be related to him through the Healy side, though, too, as her great-grandmother was Margaret Healy, who married Denis Lynch -- they were the parents of her grandfather, Thomas Lynch, the one who married Hanora Sullivan, daughter of Denis Sullivan and Mary Sullivan of, I believe Gurtnascea.  So it's a real mess!  I do know that my great-great-grandparents, Thomas Lynch and Hanora Sullivan Lynch lived "next door" to Jackie Healy-Rae's family in Reighcuslagh and that Jackie Healy-Rae knew them -- Peggy told me a story of Jackie and my great-great-grandfather Thomas, Jackie being a child at the time and Thomas being an old man.  I've DNA matched with Sullivans in the northeast...I cannot remember if they are in New York or Massachusetts, whose Sullivan ancestors hailed from Kilgarvan as well.  I've seen some of the pictures of their ancestor and her two sisters, who I suspect were probably cousins of my great-grandmother, Margaret Lynch Wall, daughter of Thomas and Hanora, because there is such a strong family resemblance between them and my grandmother Sally, who seemed to have inherited more of a Sullivan look than a Lynch one from her mother Margaret.  I just cannot find where the link is in the chain that connects my Sullivans to any of theirs.

John, are your DNA results up on GEDmatch.com, by any chance?
