If He didn't come to America by way of Ellis Island.....! [25]
DominoDo you know which state your relative stayed in when they arrived. You can try this link it is how I found my grandfathers naturalization papers.
genealogybranches.com/naturalization.html
as far as which ones to get the petition is the earlier of the 2 documents, both documents have very similar information on them. the second document is nice to get also because it was the later document (usually 5 years) and includes spouce information and children and thier current address. For persons seeking women relatives:
From 1855 to 1922 alien women became citizens automatically if they married an American citizen. Women could derive citizenship from their spouses until 1922 when the law was changed... ( This is not necessarily a dead end if you know the husbands name and where he was naturalized, his Petition for Naturalization includes some spouce information including where spouce was born)
After 22 Sept 1922 an alien woman who married a US citizen could skip the Declaration of Intention and file for a Naturalization Petition. But if an alien woman married an alien man (after 22 Sept 1922) she would have to start her Naturalization proceedings at the beginning with a Declaration of Intention.
