The following is from the Dictionary of American Biography
VII:254:
The son of a wealthy Catholic gentleman converted when very
young, by William Brewster, to Puritanism. He was a member of
the Scrooby congregation before their emigration and either
went to Holland with them or followed them after a residence at
York. He is one of the three emigrants to America who can be
traced to the Scrooby district, the others being Brewster and
William Bradford.
Before that, he was said to be a merchant of Harworth,Notts.,
and to have come to Austerfield, Yorks.
A Thomas Morton, Jr., came over in the Ann the same year and
his father, Thomas Morton came over in the Fortune in 1621.

From Dunham Family's American Heritage website
(http://members.mint.net/caronfam/heritage/regmort.htm) :

"served as an agent in London for the mayflower; reportedly
published the first news of the Pilgrim's settlement in New
England in 1622 'Mourt's Relations; came in the 'Ann' in 1623,
travelling with manasseh Kempton, and perhaps a brother,
Thomas. Juliana (his wife) was perhaps the sister-in-law of
Gov. William Bradford, William taking for his second wife Alice
(Carpenter) Southworth, widow of Edward and reportedly sister
to Juliana. The division of land in 1624 shows George and his
family being counted with Experience Mitchell to make a total
of eight."

"George d. less than ten months after his arrival, leaving a
wife and five children." His passing is noted as follows in
NEW ENGLAND MEMORIALL, written by his son Nathaniel:

"(Mr. George Morton) was a pious gracious Servant of God, and
very faithful in whatsoever publick Imployment he was betrusted
withall, and an unfeigned well-willer, & according to his
Sphere and Condition, a sutable promoter of the Common Good and
Growth of the Plantation of New-Plimouth, labouring to still
the Discontents that sometimes would arise amongst some
spirits, by occasion of the Dificulties of these new
beginnings; but it pleased God to put a period to his dayes
soon after his arrival in New-England, not surviving a full
year after his coming ashore. With much comfort and peace he
fell asleep in the Lord in the Month of June, Anno 1624."
(p.48)

Places him on a list of "Some Plymouth
Families with connections to Scituate". March 1999

Information from another source (Internet) said he came to
Plymouth in the "Little James" in 1623 along with Mrs. Juliana
(Carpenter) Morton.
