Hello. Mazowia or Mazovia is a large province that includes Plock and Warsaw. My group of families come from an area west of Plock. My great-great grandmother was Proxeda Goczynski or Goczycki or some variation. She married Nikodim Bonkowski. They were related to the Arminskis, Leszczynskis, Krystyniaks, etc. Raciaz is a ciyt like a county seat which is in this area, so there could be a connection. Does any of this sound familiar? The parish name doesn't sound familiar.
