I've hit a dead end and am just reaching out to this board to see if anything surfaces...
Looking for information on a John Twardowski who had at least one daughter by the name of Cecelia Twardowski. John and Cecelia were almost certainly both born in Poland, most likely in the Galicia region.
Cecelia Twardowski (1860 - 1937) married a Walenty Kocur and she came to America residing in Baltimore approximately 1910 - 1914. I'm guessing John's birth year to be in the 1820 - 1840 range based on his daughter's age. It is unknown if John ever came to the US.
