Firstly, welcome to Wikitree. You seem to be making good progress with your tree.
If you go back and edit this question, I think you can change the question type to Genealogy Help, or something like that. It will let the right people know that you are looking for assistance. Also, add to the tags, Jewish, and Poland, to get attention from those working in that area. If you are struggling to find any information to get back further. Also include brickwall on the tag for this question.
The other thing that you can do, is put up Segal-470, in the space provided, so that your question has a link through to where people can look at your profile and help.
Keep up the great work, hopefully someone with the knowledge in your area, will be able to help you soon. Keep in mind also, lots of people are working on the Clean-a-thon challenge this weekend, and help may come after that.
