Someone in my family immigrated to the United States in the 1880’s. I have been searching for quite some time for the naturalization certificates of those that immigrated.

I have found two certificates – and there were 7 males in the family.  Why didn’t all of the males become naturalized?

Voting was a good reason to become naturalized, but un-naturalized aliens usually could still own property.

The reason could be that the others never bothered with naturalization.
