Virginia,
I found you by accident. Your Rech ancestors may be from Seren di Grappa, Northern Italy. My great-grandmother was Guilia Rech who married Felice Dal Zotto. My grandmother was Virginia Dal Zotto who married Giovanni Giosta. I am their grand-daughter Virginia Daum, my mother is Clara Giosta Daum.
There are six families in Seren di Grappa who are related by marriage many times over: Rech, Giosta, Bof, Dal Zotto, Scopel and Sciarot. Many of them immigrated to Pennsylvania, USA, and to Rosario, Argentina. My grandfather was supposed to go with an uncle to Argentina in 1915, but he ended up in the USA. My grandmother Virginia came in 1922 with my one aunt.
Hope this helps. We have always wondered what happened to the family members who went to Argentina.
Virginia Daum
