My maternal family was from Dynow. I didn't find information on the Wenigs you are seeking, but I did come across the following:
-In the New York Dynower Society there was an F. Wenig member. I'm attaching a flyer from 1937 imploring members to send contributions back home to the needy F. Wenig circled. There are some photos of Wenig in the Dynower Society journals, but I don't have the copies with me as I moved recently, but when I go back to my old residence I will look. The journals are also in the collection in YIVO in NYC.
- In the Mt. Lebanon Cemetery there are buried a Hyman and Rose Wenig.
