I am searching for information concerning my grandfather, Joseph Mrozowski(Mruz, Mroz)who gave his parents names as Thaddeus Mrozowski and Cornnelia Mozelewska from Lomza, Poland. My grandfather was born on July 29, 1883. He left Lomza after the village he lived in was overrun by the Cossacks. He made his way via Germany to the US. His brother and sister were also in the US in 1903 when he married my grandmother in Camden, NJ. He was living in Philadelphia,PA at that time.
