Immigrant ancestors often went through the process of becoming naturalized citizens of the United States. A couple things to remember about this process is that it took two steps. First was intent and finally was becoming naturalized. This process takes seven years.
Prior to women getting the right to vote in the 1920's they could only beceome a naturalized citizen of the United States in one way. Their husband had to be a naturalized citizen or US born. Depending on the nationallity some never became citizens. As documents go the naturilization records both the intent and the final document tend to be a little lacking in the information area. Majority of the time they only indicate the coutry that the person orginated from, but as it goes all documents as they relate to our ancestors are good to have.
