About Pedigrees: Not sure if the film has only Tipp. pedigrees or also from other places, but there are at least forty names mentioned in the LDS film # 0100128. Of the forty, I don't see (in my scribbled notes) mention of any O'BRIEN. It might be worth a look anyway. The full name on the film is "Pedigrees from GO 1690-1829. Copied from MS 182." I'm also not sure if the film I'm mentioning isn't a copy of the one already mentioned. Good Luck! Heidi
