Plymouth County Genealogists, Inc. was founded in 1975 as part of the Massachusetts Society of Genealogists; formerly known as the Plymouth County Chapter. The group was created by a dedicated group of people who envisioned a non-profit genealogical society with these three goals in mind:
​
1) Furthering the advancement of genealogy as both a hobby and a profession
2) Encouragement  of sharing accurate documentation
3) Exploration of new avenues of research

After temporarily disbanding, the society was re-established in 1978 and incorporated in 1993, now going by Plymouth County Genealogists, Inc., with the goal of promoting general interest in genealogy while focusing special attention on the family histories and historical subjects relative to the Plymouth County area. ​​
