[Ger-Poland-Volhynia] 2 Tulowices and the polish borders of 1920

[Michael & Maureen McHenry]

I have been working my way through the parish records of Wysograd, Ilow
and Secymin looking for evidence of my grandfather. This is based on the
spelling of the town on his ships manifest. It was spelled Tolowice. I
deduced this meant Tulowice, since the polish U is an OO sound. This was
after some discussion with Jerry. My grandparents had a close friend or
relative from Kromnow so further concluded it was Tulowice near Warsaw.
Yesterday I searched for Tulowice in Encarta and came up with a second
Tulowice SW of Opole. Was this inside the Russian Poland border pre WWI?
If so were there any German villages near this one? I can't tell from
the maps I looked at. 
Also can anyone tell me how far the Polish borders extended into the
Ukraine in 1920? Did it include the Ukrainian province of Rivnenska? The
reason for this question is my aunt claimed to have been born in
Jalowice. Her mother went back to Russian Poland to have her. Some have
suggested that this Jelowica in the Ukraine. The US census required that
you give your birth place as defined by the borders of 1920. The
response of for the family was Poland.
