Can I find my ancestor's naturalization papers?
I have found some of my ancestor's citizen and naturalization documents but not for some others. Why are some available and others not available? For instance, I have found Otto Helwig's but I can not find Adolph Helwig's. Adolph was born in Lipno Poland in 1887, immigrated in 1903 and naturalized in 1916. He stayed with his bro-in-law Daniel Harke in Philadelphia when he immigrated. By 1920 he was in Detroit, Mi. I also cannot find 1910 census to see if he was with Daniel at that time.
Can anyone find these documents on Family Search? Are there other places to locate them on line for free? Seems like everything points to paying Ancestry.com
