Hello Mrs. Bruns,
I wander if there would be a link with my grandfather Eugene Charles Peeters. We all have European roots, although we were born and raised in Indonesia.
My mother, Evy Jansen-Peeters, told me a few years ago, that her father received a letter and documentation concerning a will (testament) send by German ancestors with the request to pick up his share of the will!
This was before the WW2. My grandfather never expected to go to Europe and put the letter aside. This means that my ancestors from mother's side originally came from Germany.
More info not available.
Maybe someone can give me some answers concerning abovementioned, as the Indonesian authorities destroyed many Dutch documentation after Soekarno was president!
