I didn't know your Grandad came from Austria-Hungary.
I shall try and find my Mother and Fathers citizenship papers Circa 1972.
I am certain though it was not like that however.
I like how your grandfather's assumes that A. He a Subject and NOT a citizen of a Republic.
B. Has anno domini for the year.
C. Is not an Anarchist (of course)
D. Nor are you a polygamist.
And Finally has so Help me G-d.
Oh and it is NOT written in any other language than English. Despite the fact that your Grandfather would have grown up speaking German and/or Hungarian.
My how things have changed in 101 years.
When my Italian grand parents came to this country, the first rule was ONLY ENGLISH was spoken, grand dad said you are AMERICANS NOW, learn to speak it and be AMERICANS. My dad was a 1st generation American, fought in WW2, put the flag back up on Corregidor when old Mac retook the “Rock” with another man volunteered under sniper fire, won a Bronze Star for it.
