Hi Lynn,
I was poking around in the message boards and saw this previous post. Well I have found much more on the Grzegorczyk's lately. If you are still on ancestry let me know and I will send you an invite to my tree. It is public but much easier to look around if you get into the tree itself. I have had a lot of luck in geneteka.pl finding records. Of course the are written in Polish or Old Russian. If you are on facebook.com there is a "group" that is strictly Polish genealogy. They have been a huge help at translating these old records for me. I did find my ggreat grandmothers family from Philly, by doing a dna test through 23andme.com. They are all in CT now and we get together quite often. Keep in touch and let me know how you've been doing on your family tree!!
