Curtis; Elizabeth (Hutchinson), and sons John, William and Thomas.  On August 10, 1635, the ship Safety boarded passengers for New England at London.  It was late in the season, so there must have been a rush to get underway. On the list of passengers was 21 year old John Curtis, on his way to his folks.
The senior John Curtis was at his Essex home in Nazeing as late as 1637 - that year he was assessed to pay King Charles' ship tax, levied only in seacoast counties.  But shortly afterward, the elderly couple - John was over sixty - together with their other sons Willam and Thomas aged about 20 and 16, emigrated to the Massachusetts colony to join their oldest boy. Records in Roxbury show John Curtis owning land there in 1638-40, and in 1639, a John Curtis (probably Junior) owned a homelot in Wethersfield, where many of the Essex folk who followed Thomas Hooker and Adam Blakeman lived.
John Sr. must have died in Wethersfield.  In Stratford, all records show "widow Curtis and her sons."
"A note of the estates and persons of the Inhabitants of Rocksbury" (Written between June 1, 1639 and March 1640, but without day of month being recorded)  John Corteis had 15 acres, and 5 individuals in household.
This John Corteis (Curtis) is not of further positive record in America. Doubtless, with his wife and three sons, he removed from Roxbury to Wethersfield, Connecticut, but died before he became of record at Wethersfield. His widow, Elizabeth (Hutchins) Curtis, and their three sons, John, Thomas, and William Curtis, removed from Wethersfield to Stratford, Connecticut, within the same year, 1639 or 1639-40; there was another man, Thomas Curtis, who for years did remain at Wethersfield.  The said John Curtis, the father and emigrant, was baptized in the parish church of Nazing in the county of Essex, England, as per the register of baptisms of that church, viz; "Baptisms John Curtis Sept. 15, 1577."  This John Curtis was a son of William Curtis...  (A Genealogy of the Curtiss-Curtis Family of Stratford, Connecticut - Harlow Dunham Curtis)
 

ELIZABETH HUTCHINS: Widow Curtis was Elizabeth Curtis, the mother of William and John, with whom she came to Stratford, leaving apparently three of her children at Roxbury, Massachusetts.  The reason for the seperation of the members of the family may have been the fact that the father, now deceased, had aquired a considerable property in land at Roxbury which could not readily be disposed of to advantage, and hence three stayed to care for it and three came to Stratford.  Widow Curtis' homelot was near or joining Rev. Mr. Blakeman's. She died in June, 1658, and her estate was apprised at 100 pounds 3 shillings 6 quid.  (History of Stratford, CT)
