born 28/09/1925 Bazaar, poland
There is a village Baz
ar in central Poland in Lodz Province. Double "aa" would be highly unusual in Polish locality names. There sems to be a church there, but I wasn't able to find any contact information. The small church in Bazar, belongs to the Rozprza Parish, and is located just a little south of Rozprza (drag the map a little, linked below):

I cannot believe that I have no living relatives
Sadly, you may want to consider that idea to be true. The area was relaively close to the city of Lodz which had a large Jewish population. Many Jews hid in the area's villages and if Germans found a Jew to be hiding in in a village, ofen the entire village was destroyed - i.e. all inhabitants executed on the spot. Not saying this is what happened with your family but there is that possibility.
Good luck.
