Thank you so much! I spent my morning yesterday searching through the links that you were so kind to post for me! Are you familiar with the Bockzi/Grajewo region? I've traced Seborowski back to my twice great-grandfather from Grajewo (Wiktor Seborowski) who was born sometime in the early to mid 1800's (his daughter, my great grandmother was born in 1892 there) so I think that the spelling is solidly confirmed. What do you think? Any input that you might have would be greatly appreciated... I've been tracing my father's paternal line for almost 2 years now and have turned up hardly anything on my own. Thank you in advance!
