Suggestions on Where/What to Search

That is wonderful news Joe. Where do I write to get a copy of the
Letter of Intention? I am looking for info on birthplace and exact
date of birth for my gr.grandfather. All I know is that he was from
County Cork Ireland. Any help would be appreciated.

Thanks, Ginny

Ginny,
You have to search the court records in the place where your relative filed his/her papers/application. In my case that was St.Louis, MO. since that is where he settled and thankfully didn't start the process in one location and finish it in another. I used the Census listings to narrow down the time frame and then ordered the appropriate roll of micro film from my local Family History Center library. You can also use your local branch of the US National Archives as they have all the naturalization records there as well.

Hope this helps!
Joe
