Thank you so much for all the information you provided in your 3 posts! I had previously found only the births of children of Willet & Frances Briggs through James Arnold's Vitals at newenglandancestors.org, and the burials of Stephen Briggs & wife Rebecca in Greenwood Cemetery, Coventry.
With the maiden names, places of births, deaths, etc that you provided, I can now expand my research. I'm new to Rhode Island research. What does "RIGR" reference? Books or microfilms perhaps? My local library has been excellent at ordering films & books regarding my other family lines. I'm always looking for new avenues to explore.
