Nathaniel Chauncey (1681-1756), clergyman of New Haven, Connecticut, was the first graduate of Yale College (1702). His son, Elnathan Chauncey (1724-1796), clergyman of Durham, Connecticut, was also a graduate of Yale College (1743). Elnathan Chauncey's daughter Catherine (1765-1841) married Reuben Rose Fowler (1763-1844) of Durham in 1790. Their son William Chauncey Fowler (1793-1881), clergyman, educator, and author, of Amherst, Massachusetts, and Durham, was a graduate of Yale College (1816); in 1825 he married Harriet Webster Cobb (1797-1844), the widow of Edward Cobb and daughter of noted lexicographer Noah Webster.
The genealogy, lives, and careers of Chauncey and Fowler family members are well described in the volume Memorials of the Chaunceys, by William Chauncey Fowler (Boston: Henry W. Dutton, 1858), in particular pages 93-112, 175-192, and the Chauncey family tree that folds out between pages 88 and 89.
