I could be related to the Quinn sponsors because my Gr Gr Grandmothe was Margaret Quinn who married Philip Brennan. If you check my bulletin board postings or the Brennan board, I just posted the genealogy line of this group in response to another conversation.
Also my Great Great Aunt Catherine Brennan married a Jim Maher and settled in Vernon Ct.
However, Quinns, Mahers and Brennans are so prevalent in Strogue and Castleiney, it will be an effort to prove the relationships. Good luck!
