I know its been awhile since your post, but I think we have the same family in our family tree. My Great Grandfather was Robert Jablonski, born in 1897 in Holland, Ohio (not positive on Holland). He had 3 brothers; Charles, Casper, and Leo, and 1 sister, Pearl Snopkowski (Jablonski). Robert Jablonski married Rose Wawrzyniak and had 2 sons, Ronald and my grandfather, Richard. Richard Jablonski had 1 son (my father) Robert and 1 daughter, Kathy.
I just started looking into the Jablonski family tree about a month ago and can't find much at all on the Jablonski's.
