John Hiett (son of Unused Data Hiett) was born Abt. 1674 in England, and died 
Aft. 1726 in Bucks Co., Pa.. He married Mary Smith, daughter of William Smith and Grace ?.

The actual English lineage of John Hiett, the Quaker who came from
England to Pennslyvania in 1699, has not been traced, but it is estimated
that by the first census of the United States in 1790 one out of every
five thousand individuals was a Hiatt by some spelling and some were in
almost every state of the union. The only clue that we have as to the
English home of our earliest known ancestor, John Hiett is from a book
"A Collection of the Sufferings of the People Called Quakers". That book
mentions a John Hyott of Shipton-Mallett who was taken prisoner in
Somersetshire in 1683 during the Quaker persecutions. There are
traditions that John Heitt escaped from England to Holland or France
during the latter part of the seventeenth century, and while there are a
number of versions of the family traditions, the typical tradition of the
Quaker Hiatts is "Our ancestors were Quakers who came from England to
Pennslyvania with William Penn." One variation mentions that there
were three Hiatts who came over with William Penn who were brothers
and Quakers, and that one of them returned to England. No record of the
other has been found and the three brothers probably actually refer to
John Hiett's three sons. It is known that Wm. Penn's second voyage to
Pennslyvania was in 1699, the same year that John Hiett came to this
continent. The next year John Hiett purchase three hundred acres of land
in Bucks Co. Pa. for three hundred and fifty pounds "Current silver Money"
(about $1500). There are numerous records of land transactions after
that involving John Hiett, but no others involving any other Hiett that
could possibly be this ancestor; however, his name does not appear on
any of the early Quaker Monthly Meetings. Either he had simply not joined
any Monthly meeting, had been disowned for some infraction of the rules,
or may have been too far away from any of the gatherings to attend. His
wife's name was Mary and a Mary Hyot is mentioned as a member by
certificate in one of the early meetings in 1707. There is no other Hiett
by any spelling found in that region so Mary Hyot was probably John
Hiett's wife. Perhaps she was simply a more diligent Quaker than he.
John Hiett is listed in the early deeds and records as John Hiett
"yeoman". A yeoman was a freeborn common man of the most respectable
class; a freeholder. Although John Hiett was a land owner, he was
apparently primarily a merchant which is how he acquired that first 300
pounds to purchase his first land.
