Anyone live near St Andrzej's Church in Osiek?

I have a favor to ask, If anyone does live close to this Church,
I want to explain first , During the war, my uncle had recieved a letter
from two nieces (he didnt believe they were who they were) stating who
they were and they wanted to come live with him, because their parents had
died. MY Grandmothers sister Married a French soldier. This is what was told by
one family member who says my great Uncle told her. of course all these folks
are gone. as they are older, except the one who told me, she is alive in a nursing home
now. she said that her father didnt respond, but that the letter had said that they
were living with the Organists of the church they went to in france. apparently he had
been raising them. we dont know when their parents died, because no one saved these
letters.
to get on with this story. Ive been tracing and tracking my family since 2001. and I have
alot of info, but the one thing the priest didnt give me was my Aunt Elizabeths husbands
name or last name. who she married. I have the Marriage date, and her name, and
that is it. I could probably find this family if I had the last name of who she married which
is in the church, I have had a time communicating with the former Priest who had done
the genealogy. he was so helpful. All i need is the last name of her husband for my
great Aunt. the marriage date was 10/5/1922 she was born 1902.

Any help to call the church (only if you are close to it) would be sooooooooo
Appreciated.
as it stands now, no one knew that they had tried to contact the family, had my
grandmother known, she would have had them come here, but because it was my
great Uncle and his wife was very awkward and mean, (his wife) I believe he would have wrote to them, but we have heard stories, and unfortunately they are still like this and
wont even help me, and we do know them. they just are very inward family and it
dont make sense, but I dont care to make sense of strange, when all i want is to find
my aunts childrens family, which might still be in france, maybe back in poland or in the
UK even. her name was elzbieta Luranc. or Elizabeth Luranc Slub 10/5/1922.
married at St. Andrzej's in Osiek, Malopolskie Poland.

also, I questioned why he would not have included his name when he sent me this
but, still no answer. if anyone could contact the church and just give me her husbands
last name that would be awsome. my one wish was to have all the family included in
our family history as much as possible. if they cant be found I cant control this, but
I feel horrible that my great uncle would not even acknowledge a letter that was
probably them. my thoughts are that it was, because you cant write letters to someone
if you dont know what the address was , if they had their mothers belongings, they had to have had his address in the belongings.

Please any help out there in or near Osiek, Malopolskie?

Patrycja aka patty

do you speak/write in Polish?

nope, wish I did, no one taught me growing up, so, my future plans are to take
classes here where I live as it is a very polish community.
