My Belcher family built a home in 1666 in Braintree. The Adams family 75 feet from this home tor generations. Eventually John Adams purchased the Belcher home. He thought it was better situated. Both homes are now part of Adams National Park which also includes Peacefield down the road several blocks.
In the correspondence between Abigail and John Adams the Belcher family is referred to several times as John was gone often and Abigail needed help with the farm and other issues with the household. The actual handwritten letters are indexed and can be read on line, including their transcriptions.
My Belchers came to San Francisco about 1900 but most of of Belcher cousins still live in or near Braintree 350 years later.
My family knew nothing of any of this until I started researching our genealogy in 1998.
