Yes, I've heard of John and Harold both. Was your mother called "Kate"? I also grew up on Long Island. My father's nickname is "Bubby", you may not have heard him referred to
as Tom - he is 82. I live in the Lehigh Valley in PA.
The only change I know of in the name was the dropping of the Von -- was there any further change? I have found an extremely interesting link to Prince Maximiliam zu Weid-Newied. Do you know anything about Carl Von Braunsberg -- or Baron Von Braunsberg? Feel free to contact me privately if you wish at CRogosky@aol.com
Wonderful making this connections with you!
