GGF Never Naturalized - How to Prove?

[mattera]

Hello,

My great grandfather never naturalized, but remained an alien all his life in the US. He immigrated in 1912 and died in the US in 1946. How do I prove that he never naturalized?

Perhaps this site can help...I know writing to Lee's Summit helped me in the past. I used this form and the complete file.

Also, here is a thread on another site which discusses various issues on this same topic.
