Hugh:
The first thing you need to do is find Dr. McInerney's death certificate and marriage certificate. They should tell you his mother and father's names. You cannot find anything in Ireland unless you have those names, especially the mother's maiden name. If he was born in County
Clare, your parents can take that information to the
Clare Heritage Centre in Corofin, County
Clare. They will research the family for you. Since he was born fairly recently (1880), you should be able to find a good deal of information, and maybe even connect with current family members in Ireland. Since he lived much of his life in 20th century
New York, was a medical doctor and lived on
Park Avenue, you should find plenty of information on him without a lot of effort. Minnesota has a history center that provides tons of genealogical information. I bet
New York does too. The easiest way to start is to go to Ancestry.com's home page and enter is name. Narrow your search to the state of
New York and you'll be surprised how much will come up. My ancestors were illerate farmers from
Corbally townland, County
Clare, near Kilkee. They left around 1849. Few records survive in Ireland from that era. Your ancestor shouldn't present too many problems. Hope this helps.
