My paternal great-grandmother's maiden name was Mathilda Inderbitzen and she was born in 1866 in Schwyz Switzerland. Her father was Gustav Inderbitzen. She had brothers named Edward, Otto, Gustav and a sister named Rosa Inderbitzen. She immigrated to the US a few years after she was born and they lived in Pittsburgh, Pa. She died in 1952 in Pittsburgh. She had uncles in Switzerland named John Robert Inderbitzen, Melchior Inderbitzen, Leonard Inderbitzen and Joseph Inderbitzen. Also a cousin named Eliza Inderbitzen.
That's about all I know. If anyone has a connection, please advise.
