COMUNITATEA FR. ROMANIA CU BISERICA SF. IOAN THEOLOGUL, CUCOVINO PROVATA DIN SF. MUNTE ATHOS
Romanian Front (Frontul Român [http://en.wikipedia.org/wiki/Romanian_Front]) community with the church of St. John the Theologist (Ioan Theologul [http://www.in2greece.com/english/places/summer/islands/patmos.htm]) (CUCOVINO PROVATA - are you sure that it is spelled right??) from St. Mount Athos (http://www.inathos.gr/)
Mount Athos is a men's only monastery, so you great-grandmother might have relate to St. John's church, in Greece.
