I'm sorry...I didn't get notification of your last posting!
I understand your theory about Poles/Russian occupation, et al however it is not completely accurate. Our family, another 3 branches of the POLISH side, still live in the same villages and some in the same homes as they did prior to WWI. Our grandfather's home(Stankiewicz and Winiewicz), down the road from Ferma-where our Gudalewiczes(Juszkiewicz) are from, is lived in by a cousin and her family. Our Gudalewicz was a female but her brother, Seraphim(?)lived with her/her family, according to 1910 and 1920 US Census. I don't know if he ever married. There was another Gudalewicz family here but the man never answered my letters. I was told they were related (Edward G.) from an old dear cousin who knew his sister, Pauline. I am still awaiting word from Lithuania with more info on the Gudalewicz tree. It takes a while to get info. Let me dig out my Gudalewicz tree, however limited, may have some hidden treasures. BTW, do you want my email? It may be easier for communicating.
