I requested official certified copies of the 1900, 1910, and 1920 US census showing my great-grandfather, Angelo Palmeri. They arrived today. The 1910 is from Pennsylvania, where he and his brothers were coal minres. The 1920 and 1930 are from Buffalo.
Now if they could send me something on his naturalization, I'd be happy.
