My mother’s family comes from Wysokie Mazowieckie as well. Jewishgen recently published a translation of the Yizkor book for this town which features a history, pictures and first hand accounts about the town. The book does not go past the Holocaust since that marks the end of a Jewish presence in the town. Some and perhaps all of the book’s contents are on jewishgen but it can be purchased here:

There is a local teacher (Karol Globocki) who heads a yearly clean up of the cemetery that still exists and is knowledgeable about the history as well. You may also find the Facebook group Suwalk-Lomza Independent Jewish Genealogy Research Group useful for your research. We are all researching the region and being able to “talk” with others with a common interest can be invaluable.

Good luck in your search!
