Jerry,

There is also an Ellis Island website, it is supposed to have quite a bit of information on it. I don't know the web address, If you do a google search you can find it. If your family came through Ellis Island you might be able to find the information.

The US Government has some websites that release information on various subjects say after it is 50 years old, they just released the 1920 census information a few years ago.

If your Uncle is deceased, you might be able to find some information on his Death Certificate, You can obtain a copy, for a small fee, from the state he resided in at the time of his death.

You can also try leaving a message on one of the message boards for his surname and his wife's surname at www.rootsweb.com some one out there may surprise you and have the information you are looking for.

Look up the website for the Irish Counties you mentioned, most of them have websites, sometimes there is a surprising amount of information on some of them. You might pick up a clue.

Hunting for some of this information is like hunting for a needle in a haystack and it can take a long time to find.
