Well, I think we are coattail relatives! Is that how the saying goes?
I think the original Michael Horgan I was referring, who left Ireland in 1850, left with an older brother named John. I believe he settled on the east coast, and I think his son is the Michael Horgan you may be referring to. Does this sound possible? Do you know when John Horgan left Ireland, and where he came from? The emigration I am referring to happened in 1850 from around Killorglin, Co. Kerry. A John Horgan, Michael Horgan, Abigail Horgan, and Patrick Horgan, all young adult siblings, sailed out of Queenstown (now Cobh), Co. Cork on the ship Uranus bound I think for Boston. I have the details recorded by Michael Horgan Jr., the son of the Michael who made that journey. Feel free to e-mail me and tell me what you think. I am going to graduate school in Ireland for two years, starting next month, and would love to make some contact with some Horgans there!
Best wishes and hope to hear from you,
