Thanks for responding to my email. To see more information on what I know of my McCarty tree with roots in Athenry, you can use the following url http://wc.rootsweb.ancestry.com/cgi-bin/igm.cgi?op=SHOW&...
My great grandfather, Thomas, emigrated around 1858, settling in the Boston area. Other McCartys were already living there according to family history. Thomas was son of Patrick McCarty and Maria Manning, according to what i've been told.
Recently I joined the McCarthy Y DNA project, headed up by a fellow named Nigel McCarthy. His email address is firstname.lastname@example.org
He has been very helpful.
I took the 37 marker test and my results were distinctly different from most of the other McCarthy/McCartys who had been tested.
That's why I've been trying to track down others with the McCarty surname, who also have ancestral roots in Co Galway
My impression is that my Athenry McCarty ancestors emigrated 1840-1860 to various locations US, England, Australia etc. One relative has suggested that they may have earlier come from the Aran Islands, though others are skeptical.
Let me know if you have trouble with the Worldconnect URL or have any other questions.
