When James left his home at Fairsted, he left in its burying place his wife and four of their seven children.  James Olmsted, together with two sons, Nicholas and Nehemiah, two nephews, Richard and John, and a niece, Rebecca, came to New England in the ship 'Lyon,' under Capt. Pierce, arrive at Boston on the Lord's Day 16 September 1632, after a voyage of twelve weeks from Braintree, England.  There were 123 passengers, of whom 50 were children.  They soon settled at Mount Wollaston, now Quincy, near Boston, but in the course of a year, they removed to New Town, now known as Cambridge, Massachusetts. James was made a freeman 6 November 1632 and was chosen by a popular vote 3 November 1634 to be the Constable.
