Perhaps if you contact the Church listed in the obit, Holy Rosary Catholic Church, they might know her as a parishioner.Better yet, there are 82 entries in Joseph Papsodora's guest book.Perhaps your cousin might know some of the posters, and can these posters can be contacted via the guestbook.Hope this helps.Annie
