The Archival Task Force ran a campaign to attain funding for the cataloging of First Church in Boston records, dating back to 1630, which are held at the Massachusetts Historical Society. The trustees and several congregants contributed to the effort (thank you!) and it was completed in Fall 2021.
The Massachusetts Historical Society is pleased to report that it has finished the guide to the First Church in Boston records, and it is now available on their website. You can find it here.
