Kathy, I have come across some info on ZERUIAH Briggs. Son of Mr Josiah and Eunice Briggs. This info is received from the book "The grave stone records of Shaftsbury, 1911. ZERUIAH Briggs son of Mr Josiah and Mrs Eunice Briggs. died Sept 10, 1799 age 6 yrs 4 months, 11 days.
There is also a Mr John Briggs listed as buried in Shaftsbury. Mr John Briggs died March 24, 1813 age 58 yrs 9 months, 24 days.
Have you seen this information? I have not followed up or confirmed this info as of yet but thismay very well be a sibling of our Amyntus Briggs Sincerely Lisa Christensen
