In my searching I have not come across any Beckman's that was spelled that way. I have found that my relatives basically lived in the Seabrook, NH area. I have gone through old census,birth and death records. It has been a tedious one as some of the records weren't written that well. Feel free to write me for any information that you might be looking for. I have slowed down on the looking but I do work on it from time to time.
