English (Northumbria) : occupational name for a breeder or keeper of horses, from Old English stÅd ‘stud’ or stott ‘inferior kind of horse’ + hierde ‘herdsman’, ‘keeper’. There is a difficulty in deriving this name from Old English stÅd in that stud is not recorded in the sense ‘collection of horses bred by one person’ until the 17th century; before that it denoted a place where horses were kept for breeding, but that sense does not combine naturally with ‘herdsman’.The Stoddard family of Boston, MA, was introduced by Anthony Stoddard (1600–1686), who settled there in 1639. Solomon Stoddard (1643–1728/9) was a prominent Congregational clergyman in MA, the grandfather of Jonathan Edwards, and progenitor of many noted descendants.
