"...Jacobus Gerristen Strycker, or Jacob Strycker, as he seems to have
generally written his name, was a younger brother of Jan and came from
the village of Ruinen, in the United Provinces, to New Amsterdam, in
the year 1651. On February 11, 1653, he bought a lot of land "on west
side of the Great Highway, on the cross street running from the said
highway to the shore of the North River, Manhattan Island." A part of
this "lot" is still in possession of the family. He was a great burgh-
er of New Amsterdam in 1653-55-57-58-60. In the month of March, 1653,
he appears as subscribing two hundred guilders to the fund for erect-
ing a wall of earth mound and wooden palisades to surround the city
of New Amsterdam to keep off the Puritan colonists of New England and 
unfriendly Indians. On May 27 of the same year the worshipful schepen,
Jacob Strycker, is the purchaser of a lot of land ten rods square on
what is now Exchange Place, east of Broad street. 


About the close of the year 1660 he removed to New Amersfort, Long
Island, now called Flatlands. He must have returned for a time to New
Amsterdam, for in 1663 he appears again as an alderman of the young 
colony there. In the year 1660 he and his wife, Ytie (Ida) (Huybrechts)
Strycker, whom he married in Holland, and who bore him two children,
a son and a daughter, appear on the records as members of the old 
Dutch Church of New York, and it is noted that he had removed to New
Amersfort. The records of the church in the latter place shows both of
them as members there in the year 1667. On August 18, 1673, he became 
schout or high sheriff of all the Dutch towns on Long Island, a posi-
tion of influence and responsibility at that time. He was also a dele-
gate to the convention, March 26, 1674, to confer with Governor Colve
on the state of the colony. 


He seems to have been a gentleman of considerable means, of much offi-
cial influence and of decided culture. He died, as we find from the
church records kept by Dominie Casparus Van Zuuren, in October, 1687.
From this date until the present time (1906) the family genealogy has
accurately been traced down by General William S. Strycker, whose bio-
graphy we here append, drafted and adopted by the Military Order of the
Loyal Legion of the United States Commandery of the State of Pennsyl-
vania shortly after his death."
