Jacob Dircks was the younger of the two sons born to Dirck Volckertszen De Noorman and Christina Vigne and the seventh of their nine children. Jacob's birth year is thought to have been in 1646, making Jacob about three years younger than his only brother, Volkert.
It appears that Jacob was less successful than his siblings, as his property amounted to about a quarter of what each of the rest had. On the 'Assessment Roll of the Real and Personal Property in Boswyck, made up on the 19th August, 1675' (when he was about 29 years old), he was listed as:
Dierckse, Jabecq: 1 poll, 1 horse, 1 ditto of 3 yrs, 1 cow, 1 sheep, 5 morgans of land...53. 10 pounds
However, a year later he had doubled his land holdings, for on the 'Assessment Roll of Boswyck made up 23 Septemb. 1676' he was recorded as:
Dierckse, Jabecq 1 poll 2 horses 1 do of 1 yr 2 sheep 10 morgans land 65 18
Jacob's appearance on assessment rolls Boswyck in 1683 showed a possible reversal of fortune:
Dirckx, Jacob: 1 poll, 1 horse, 7 morgans of land 44.
His name also showed up on a protest against the salary of Rev. Dominie POLHEMUS. The last record of him was in 1689 when he sold property to his brother's son Dirck:
"17th July, 1st year of William and Mary [1689], Jacob Dirckse by and with consent of Barent Flacxbeeck, Pieter Schaimpe, Jurian Nagel, Hendricus Defforeest, William Aertsen and William Huddleston conveys property in Bushwick to Dirck Folkert."
July 17 1st year of William and Mary, Purchased from Jacob Dirckse land at Bushwick, bounded East South and west by land of widow Folkert."
[Kings Co. Deeds, 1:63-MsRec 264]
It is unknown whether he married. He did not appear on the 1698 census, and the family tree by Chuck Fulkerson indicates he died in the year 1700, at around the age of 54.
