From Deane's History of Scituate:5
"Cornet Robert Stetson received a grant of a considerable tract of land 1634, from the Colony Court, on the North River, which constituted his farm. His house was on a beautiful plain near the river. An unfailing and valuable spring, out of which eight generations of the family have been supplied, marks the spot. 'Cornet's Rocks,' in the river east of his farm, are well known to those who navigate the river. He was posessed of considerable wealth, an enterprising and valuable man in th plantation, a deputy to Court, a Cornet of the first light horse corps raised in the Colony, a member of the Council of war, a Colony commissioner for selling the patent line–in short, he lived long and left a good name at last. ... In 1660, and several years subsequent, 'Cornet Stetson was Commissioner to act for the country in all matters relating to the trade at Kennebec.' Also, 1665, for his services he had granted to him '200 acres south of Mr. Hathaerly's grant, above Accord pond.' Colony Record"

Since Robert & Honor's daughter Urith was baptized in England in 1636, they probably did not arrive in New England before then. Robert was appointed one of Scituate's two constables on 7 Mar 1643, so he probably arrived by 1642.246
