The fourth large parcel of the bouwland, called the second or foremost piece of land to distinguish it from Van Curlers,which was called the first piece lay next west. The east line of this tract ran along the west fence of the Schenectady car works yard, and so northerly to and around the east side of lot no.1 belonging to Arent Bratt, following the small brook, emptying into the Binne Kilt a little east of the farm buidings of the late John Myers. The western line of this parcel was the Poenthes Kill.
The following from John E. Sherman #47749330 Dec 12,2018 whose wife is an 8th great grandaughter:
According to our family records -- Arent Andreissen Bradt (Bratt), "de Noorman", was born in 1618 at Frederickstad, Ostfold, Norway to Andries Arentse Bradt. There is a legend that his mother was a Mohawk woman named Kinetis or Kenutje, but there is no positive proof of this. However, I believe this is highly unlikely because Arent and his brother Albert came to America from Norway, settling in New Amsterdam. Some researchers now believe his mother's name was Aefje (Eva). Arent left Texal, Norway October 8, 1636 with his brother Albert and they arrived on the ship RENSSELAERWYCK at New York March 4, 1637. After his arrival in America, he worked for his brother Albert as a tobacco planter. After ten years, he ran a sawmill, did some trading and may have had a tavern. It has been claimed, but again no real proof, that Arent married Kenutje Hertel, daughter of Jacques Hertel and an Indian woman. Arent did marry Catalyntje De Vos in 1648 at Albany, Albany County, New York and their children were: Aeffje, Ariaantje, Andries, Cornelia (#83441117), Samuel and Dirck. In 1652, the family relocated to Beverwyck and then January 14, 1653, he took the Oath as a citizen of Beverwyck. In 1658, he leased an island in the Hudson and paid rent with wheat and oats. In 1662, he was among the first patentees of Schenectady, but probably never lived there because he died soon after, November 12, 1662 and was buried in Albany.
