Jeremiah Peck, the son of William, was born in 1623 in London, and came to Boston with his parents in 1637. He was an educated man, having graduated from Hardard College, according to statements from The History of Colonial New Haven by Edward Atwater. Harvard College was founded in Cambridge, MA in 1636.
In 1656 he was hired to teach school in Guilford, CT where he remained until 1660 when he accepted the position to teach grammar school in New Haven. This position was short lived though. The New Haven Colony was suffering financial difficulties because of its legal struggles with Connecticut. Connecticut was assuming the title to the Territory of New Haven Colony and New haven was fighting them. New haven lost the fight about 1664 and was absorbed into Connecticut, but it forced the closing of the school after 2 sessions.
In 1661, Jeremiah received a call to the church in Saybrook, CT and pastored that church until 1667 when he packed his family and moved to Newark, NJ. By 1672, the family had returned to Connecticut to settle in Greenwich. Bother Jeremiah and his son Samuel are listed as freemen in the town records that year. He became the minister in the Congregational Church in Greenwich until 1789 when he went to Waterbury, CT to help establish the first church there and serve as its minister.
