Dear Mr. Whewell,
Thank you for posting your request on History Hub!
We suggest that you use any names obtained from suggestions from the previous post Seeking birth certificate of Paschal Ormsbee, to continue searching the family lineage of Paschal Ormsbee. We also suggest that you search the Massachusetts, Town Clerk, Vital and Town Records, 1626-2001 and contact the Rehoboth Antiquarian Society, the New England Historic Genealogical Society and the Massachusetts Archives for records of the family. In addition, the FamilySearch Research wiki for Bristol County, Massachusetts Genealogy may be useful.
We hope this is helpful. Best of luck with your family research!
