I would like to hear descendants of de Grussa. Most of de Grussa were from Olivine. My great great great grandfather Ambrogio were born in Olivine around 1829. He moved to London and “married” to Catherine Hopkins. Ambrogio’s parents were Carlo Antonio Luigi de Grussa and Lucia Bini. Please contact me about any of de Grussa ancestors in anywhere of Switzerland. Regards, Steven from Melbourne, Australia.
