I have a copy of the naturalization certificate of one family member and it shows nothing helpful. You need to find a copy of their letter of intent. That is the document with lots of info. But remember they may file a letter of intent one place and get their naturalization certificate in a different state. Dear Fellow Listers, I have found that different naturalization records contain different information, some more helpful than others. However I, personally, have found at least something of interest in each of them that I've been able to locate, even if it is just to confirm information I already have. Especially if you aren't sure about information you have on an individual, this is about as close as you could get to getting it right from the horse's mouth, so to speak. The information on these documents you know is coming right from the individual being researched and is reliable, unlike the census records sometimes are. Good Luck and Happy Hunting!
