At first I thought it was Rachwalowice, but there was no Wola Rachwalowice around there. Then I searched in www.stevemorse.org for Wola Rachwalowska and found out five people who come from the same place, in the same ship.
Curiously, the first immigrant is listed as coming from Wola Rachwalowska, but the others are listed as from Wola Rafalowska, then in Galicia, now in gmina Chmielnik, powiat rzeszowski, woj. podkarpackie. There is another Wola Rafalowska, but that one was not in Galicia.
In my previous search for Rachwalowice in SGKP I found out that it was also know as Rafalowice. Therefore, if ´chw´ sounds like ´f`, it is my guess that yours Rachwalowska was also known as Rafalowska.
