I am not on Facebook, but I will be soon. Let you know.
Christian Fjerdingstad lived in l'Isle Adam, a little town near Paris. Later they moved to Taverny, where he died.
My great-grandfather Karl Peter F. was a keeper of the lighthouse on Christiansø. Later the family moved to Rubjerg Knude. around 1906.
Karl Peter seems to have two brothers: Vilhelm and Albert.
Their parents had a music shop in Copenhagen.
Christian F has been married twice. His first marriage with Wilhemine von Weiler, a Dutch girl, he met in Denmark. They had two daughters: Helga (my mother) and Isabelle.
After the divorce, my grandmother went back to Holland. Later my mother and her sister also came to Holland. That is where I live.
I have some notes on older Fjerdingstad familymembers, which I cannot exactly pinpoint right now. There is mention of Jules Christopher F. born 1828, Karl Peters father ????
I will be in touch, hilsen, Christian.
