His Wikitree profile is Wiedner-45.
He was born Bruno Bernhardt Wiedner in Schwetz, West Prussia on 10/06/1870. (The town is now Swiecie, Poland)
In April, 1890, he was gainfully employed in St. Louis, MO under the name Charles Walter. He legally changed it in 1903.
He was absolutely mum on his pre-St. Louis life (apparently even with his immediate family).
A vague family rumor existed that he had defected from the Imperial German Navy when his ship was in port in either Boston or New York. Considering his birth date and the validated fact that he was gainfully employed in St. Louis in April of 1890, the time period for the alleged activity is in a very narrow range, if it happened.
I want to validate the event or disparage the event. Where do I look?
