I'm not sure if this is the same Leo or not, but my Great Grandfather, Robert Jablonski, was born in Holland, Ohio in 1897 (?) and had 3 brothers; Charles, Casper, Leo and a sister named Pearl. He married Rose Wawrzyniak and had 2 sons, Richard and Ronald in Toledo, Ohio.
I'm having a hard time researching the Jablonski family tree. My Grandfather, Richard Jablonski didn't talk much about his family. I'm trying to find out where they originated: Poland & Germany or anything else about the Jablonski side of my family.
