Elder John Strong was born between 1605 and 1609 at Chard or Taunton,
Somerset(shire), England. He passed away April 14, 1699 at Northampton, Hampshire County, Massachusetts, now USA. Some have suggested that his mother was Eleanor Deane. So far no historical evidence has been cited for these relationships.
He married twice. The first marriage was in England, about 1625 to Margery Deane. She was mentioned in her father's will by married name.  She died shortly after arrival in Massachusetts on the Hopewell. One son from this marriage, John Strong, survived.  Anderson believes that the story of her newborn also dying at the end of the voyage may not be factual. 
John Strong married as his second wife Abigail Ford in 1635 at Hingham, Massachusetts. According to Stiles, sixteen children were born to this marriage. . The Great Migration lists only 15 children, omitting Josiah Strong.
The Strong family moved from Dorchester to Hingham to Taunton, Massachusetts, then to Windsor, Connecticut, and finally to Northampton, Massachusetts by about 1659.
John Strong was a tanner by occupation. He held the office of constable at Taunton and Windsor. He was elected ruling Elder of the church at Northampton. John Strong can be credited as being a founder of the following towns: Dorchester, 1630; Hingham, 1636; Taunton, 1638; Windsor, 1646; Northampton, 1659.
From Dwight's History of the Strong Family:
"John Strong was born in Taunton, England, in 1605, whence he removed to London and afterwards to Plymouth. Having strong Puritan sympathies he sailed from Plymouth for the new world, March 20, 1630, in company with 140 persons, and among them Rev. Messrs. John Warham and John Maverick and Messrs. John Mason and Roger Clapp, in the ship Mary and John (Capt. Squeb) and arrived at Nantasket, Mass. (Hull), about twelve miles southeast from Boston, after a passage of more than seventy days in length, on Sunday, May 30, 1630.
"In 1635, after having assisted in founding and developing the town of Dorchester, John Strong removed to Hingham, Mass., and on March 9, 1636, took the freeman's oath at Boston. His stay at Hingham was short, as on Dec 4, 1638, he is found to have been an inhabitant and proprietor of Taunton, Mass., and to have been made in that year a freeman of Plymouth Colony. He remained at Taunton, as late at any rate as 1645, as he was a deputy thence to the General court in Plymouth, in 1641, 1643, and 1644. From Taunton he removed to Windsor, CT, where he was appointed with four others, Capt. John Mason, Roger Ludlow, Israel Stoughton, and Henry Wolcott, all very leading men in the infant colony, "to superintend and bring forward the settlement of that place," which had been settled a few years before (1636) by a portion of the same colony that with him had founded Dorchester. Windsor was in fact called at first, and for several years (1636-1650), Dorchester.
"In 1659 he removed from Windsor to Northampton, Mass., of which he was one of the first and most active founders, as he had been previously of Dorchester, Hingham, Taunton, and Windsor. In Northampton he lived for forty years, and was a leading man in the affairs of the town and of the church. He was a tanner and very prosperous in his business. His tannery was located on what is now the southwest corner of Market and Main streets near the rail road depot. He owned at different times, as appears by records in the county clerk's office, some two hundred acres of land in and around Northampton."

I posted this on John Strong's father's page, but I suppose it should be repeated here. I don't think there is any evidence that Elder John Strong's mother was Eleanor Deane, and I don't think there's any evidence that his grandmother was Ann Bond. Both of these appear to be internet fantasies. I'd like to propose this website (1) and this website (2) as touchstones for what is actually known about the Strong family in England.
