I don't have any document unfortunately, this is information I got from my father. (Passed by his mom) all I know is that the place was or is called Auleata , from the former German empire. and the territory now belongs to Russia.
His exact birth i don't have it. Might be either December 30th. or 31st. 1915
He was the third of 3 sons. The oldest : Walter Huber, then (another brother I don' t have his name), and the youngest Eugen Huber.
The three of them emigrated to Mexico, through the port of Veracruz (don't have a date available)
But I know it was before WWII and then went back to Germany for military service.
Returned to Mexico after that, then my dad was born in Mexico in 1948.
