John L. Rich was born on the 7th of November 1819 to Sarah and Benjamin Rich, in Truro, Massachusetts, on Cape Cod.
On the 5th of November, 1843, he married Catherine Williams Smith. While living in Truro, they had the following children:
- Archelaus (born 1844)
- John W. Rich
They moved to Boston Ward I in 1848 or 1849, and there they had:
- George S. (born 1849)
- Matilda E. (born 1853)
It seems that John was a teamster in 1850, but by 1860 was making a living as a grocer. However, within the next five years, he became a manufacturer of medicines.
He passed away on the 19th of March, 1865, in Charlestown, MA, of consumption. He was buried in Truro on Cape Cod.
