Swits was killed in 1641 (he was the first generation). He was killed is what was know as "Turtle Bay" or Dutch "Spuyten Duvel Creek". I found this in a book published in 1866 and it is located under the picture link on the home page..

Descendants of Claes Cornelisson Switz

Generation No. 1
1. CLAES CORNELISSON1 SWITZ was born 1590, and died 1641 in Manhattan, Turtle Bay, NYC. NY. He married ARIENTIE.
Notes for CLAES CORNELISSON SWITZ: From the book, "The Epic of New York City" by Robb Ellis, page 37, it says One summer day in 1641 a wheelwright, named Claes Smit(Switz or Swits), was busy in his lonely house on the East River far above New Amsterdam at what is now West Forty-fifth Street. An Indian appeared and asked to buy a piece of coarse cloth. When the unsuspecting Dutchman turned to get it, the redskin seized an ax and killed him. The murderer was the same Indian who, as a lad of twelve, had seen his uncle killed by Dutchmen near the Collect. Sixteen years later, a grown man, he got his revenge." In Rikers "The History of Harlem" page 132 it says, Claes Cornelissen Swits' earlier history is little known. Captain DeVries in noting the circumstances of his death, styles him a Duytsman, by which term the Hollanders of that day meant a German. But his true nationality is clearly indicated by the adjunct to his name, which when used is commonly written Switz or Switzer , and so we may accept the tradition held by his descendants that he was a Swiss. He and his family had sojourned in the Island Of Schouwen, and thence came to Amsterdam, boarding with other Germans at Peter DeWinters's inn before embarking for this country. He had been here now some five years being advanced in life, and on a chosen spot at Turtle Bay on the East River, "had built a small house and set up the trade of a wheelwright." With a still vigorous manhood, some education and means, and a fair business tact, Claes Rademaaker or Claes the Wheelmaker, as from his occupation he was familiarly called proved "a very useful man," given to his enterprises outside of his regular calling, assisted probably by his sons Cornelis and Adrian as he was by Alteras at the Otter-spoor. All this made his tragic death some years later the more regretted. He was killed by an Indian, and, strangely enough, his son Cornelis, from whom the present Swits family are descended, met with a similar fate at Harlem, as will be further noted." on page 138 it says, "The next year, 1641, brought retaliation from the Raritans, who on September 1st, swept off the settlers upon Staten Island, while Manhattan Island was already smarting under the first stroke of savage vengeance. A Wickquaskeek who from boyhood had harbored a grudge against the Dutch, because at the time, three of Director Minuit's men had slain his uncle and stolen his beavers, could no longer restrain his thirst for revenge. On a day in midsummer he entered the house of Claes Swits, at Turtle Bay,"on the road over which the Indians from Wickquaskeek passed daily." Assuming a friendly air, and being known to Swits, for whose son he had worked, he was "well received and supplied with food." Then he wanted to trade some furs for duffels; but while the unsuspecting old man was bending over the chest in which his cloth was kept, the savage, with an axe that lay near, struck him upon the neck, when "he fell down dead by the chest." He then stole all the goods and fled into the forest. This cruel murder, at their very doors, aroused the authorities, and a yacht was sent to Wickquaskeek, to demand satisfaction from the sachem. He not only refused, but justified the act. "He wished twenty Swannekins(i.e.Dutchmen) had been murdered." Because of the time of year Kieft and his citizens delayed an immediate war to avenge Swits murder. On page 161 there is reference to Claes son, see Cornelisen Swits notes.

Child of CLAES SWITZ and ARIENTIE is:
2. i. CORNELISEN2 SWITZ, b. 1614; d. September 15, 1655, Harlem Property, NYC, NY.

Generation No. 2
2. CORNELISEN2 SWITZ (CLAES CORNELISSON1) was born 1614, and died September 15, 1655 in Harlem Property, NYC, NY. He married ADRIANNA TROMMELS, daughter of CORNELIS TROMMELS.
Notes for CORNELISEN SWITZ: In Rikers "History of Harlem" page 161 it says "Very early one morning, September 15th, 1655, sixty-four canoes of armed savages landed on the beach at New Amsterdam, and before scarcely anyone had risen, scattered about the town and began to break into the houses for plunder. All was alarm and confusion, and to make matters worse, Stuyvesant was absent, having departed on an expedition to the Delaware a few days before taking with him most of the garrison. The members of the council finally prevailed with the chiefs and their people to withdraw from the city, but at evening they returned, and a skirmish took place between them and the Dutch soldiers, blood flowing on both sides. The now enraged Indians departed but on that doleful night began a horrible slaughter of settlers, full fifty of whom fell within three days, while over a hundred, mostly women and children, were carried into captivity. Hordes of armed savages, thirsting for blood, swept over these Flats and devastating their bouweries. Cornelis Claessen Swits, whose father, as we have seen, had been killed by an Indian, now owned the farm on the Flats originally granted to Isaac DeForest, but which Swits had purchased from Beeckman, March 10th, 1653, selling the latter in exchange his plantation near Curler's Hook, later known as Delancey Farms. Since his good vrouw, Adrianna, had lost her father Cornelis Trommels, of Rengerskerk, a quiet hamlet in the Island of Schouwen, what changes she had experienced! Left an orphan to the care of a guardian at Brouwershaven, she had, after other vicissitudes, found a home on these beautiful but solitary plains, Having since her arrival here inherited some property from an aunt in Zeelan. She was now the mother of five children between the ages of three and fifteen years. Swits had built a house, and labored hard upon his farm from fifty morgen, in clearing the land, etc. hoping by patient industry to cancel a debt of seven hundred guilders due the West India Company for commodities advanced to him. ...Both Swits and (his good friend) Teunissen were massacred, their goods plundered or burned, and their terrified wives and little ones captured and hurried away to their Indian haunts in the forest.....this scene was enacted over and over... The Indians had threatened to "root out the Dutch" ...nor did the they spare the English....In a few days the Indians having glutted their revenge, and willing to get the captives off their hands, made overtures which resulted in the ransom, during the month of October...but not the families of Teunissen and Swits... (it was many months before Adrianna and her children were released from captivity. Because of their long absence they eventually lost title to the land they worked so hard for, even though they tried to get the property back for years up until 1664). On page 168 there is a footnote and family list on what happened to the descendants of Cornelis Swits.

Child of CORNELISEN SWITZ and ADRIANNA TROMMELS is:
3. i. APPOLINA CORNELIS3 SWITZ, b. October 25, 1648; d. not known.

Notes for APPOLINA CORNELIS SWITZ: Last evidence for Apollonia was as baptismal witness for Antje DeVries, her granddaughter, on July 13, 1713(NYDC 2:368). Notes for JAN THOMASZEN: Last evidence found for Jan was as a baptismal witness for Jan and Apolonia Heermans, twin children of his daughter Margariet, on May 2, 1706.

i. THOMAS4 ECKERSON, b. January 27, 1668/69, BP at New York Reformed Dutch Church; d. not known; m. ELIZABETH SLINGERLAND, November 11, 1700, Reformed Dutch N.Y.C.Collegiate Church.
Notes for THOMAS ECKERSON: There is a page in the Ray Eckerson Genealogy of 1939 "Eckerson Family" that tells about this Thomas Eckerson. "Thomas Eckerson was in New York City as a resident as late as October 1704, when he was a constable in the Bowery Ward. At about that time he owned some thirteen acres and a large brick house at south east corner of the Bowery and Houston Street. The N.Y. Census of 1703 shows Thomas Eckerson as being a householder. The children of Thomas and Elizabeth Slingerland Eckerson were: Jan bp. Sep 27, 1701 Anatia bp. Dec.16, 1702 Apollinia bp. Nov 22, 1704 Teunis Bp. May 14, 1707 (above children born in New York) The family may have moved from New York City about 1710. About 1720, or soon after we find them out in the Schoharie Valley. They were among the first members and officers in the Schoharie Dutch Reformed Church, this Church having been founded a few years before 1730. (We do not know where this information was obtained. But maybe in 1939 Ray Eckerson had access to records that have since perished or have been lost--Kathy Albaum) Joined the Schoharie Reformed Church on Jan.3, 1730(NYGB 29:243). Last evidence of Thomas and Elizabeth was as baptismal witnesses for Elisabeth Eckerson, their granddaughter, on Oct.15, 1735 at the Schoharie Dutch Reformed Church.(Scho#45).
