My 76-year old father-in-law (New Jersey) came across your request for info about the Jablonski and Filipkowski families on GenForum.
He's been working on his ancestry for a number of years and has a lot of info you may be interested in looking at. He wants to connect with you. I know he visited Filipkowski relatives in the Lackawanna/Luzerne area a number of years ago. I think that's where you are.
Please contact me, if you're interested in talking to him.
