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.
