A little background info on the Chaunceys. Rev. Isaac Chauncey born Oct. 5th in Stratford, CT. married 1st Sarah Blackleach in 1697 and then the widow of Abiel Metcalf (no date and no name) Isaac the son of Rev. Israel Chauncey born 1644 in Scituate, Mass. married Mary Nichols Jan 8, 1667/8 and then Sarah Hudson (Judson?) This is from the Graham family history published in 1942 Our connection to the Chaunceys is via Abigail Chauncey daughter of Isaac and Sarah who married Rev. John Graham of Stafford Mass at that time.One of her brothers, Israel set on fire a building in which he had been confined during an attack of insanity and died of his burns.Apparently depression showed up in several generations including latter generations of Abigail's children.
