Jeff: Thanks for posting this important find on the DC mailing list. Michael Morrissey is the one who finally found the Kings Co., Land Conveyance the same week that the NY Land Deeds were posted online. I had previously searched the Kings Co. Grantee Grantor Indexes without finding any mention of the Achias/Agyas Janse Van Dyke land records mentioned both by William B. Aitken in his Distinguished Families of America p. 230 and by Teunis G. Bergen's Early Settlers of King's Co. p. 335. The will of Agyas Janse Van Dyke still remains undiscovered and perhaps was unrecorded. Most of Achias Van Dyke's children were baptized in the Flatbush, Brooklyn and New Amsterdam Dutch Reformed Churches and all of them list Jannetje Lamberts as the mother plus Lambert Van Dyke the 2nd oldest son was named after Jannetje Lamberts' father Lambert Hendrickzen Van Campen. The 1708 land conveyance also names Jacob and Janake Van Dyke for whom no baptisms have been found. Perhaps Janake/Jannetje may have been the Susanna who was baptized 16 May 1679 in the Flatbush Church. Thomas and Anna Van Dyke, known children of Agyas and Jannetje, are not mentioned in the deed probably because they were sill under the age of 21. It is also possible that Jacob was the Barent Van Dyke baptized 17 Oct 1687 in the Brooklyn Church. I have a couple of research articles I wrote on Hendrick Willemsz Van Barnevelt who is believed to be the father of Willem, Daniel, Hendrick and Francyntje Hendrickson that I can send you if you wish. The reason that this deed proves that our Hendrick Hendrickson was the same Hendrick that later married Helena Denys nee Cortelyou, as you mention, is because of the distinct HH mark (with the H's connected). The HH mark is also used on Monmouth Co., NJ Land deeds where Hendrick Hendrickson and Helena's son Jaques Deniss and Abraham Emans all of Monmouth Co. sell lands they have previously bought to Steven Aumack Recorded 29 May 1734 (Monmouth Co., Land Deeds 1697 - 1745, Vol H, pp 114-115). Hendrick purchased several Monmouth Co. parcels of land around 1720 with Helena's two sons Jaques and Tunis Denis/Denys before he moved from the lands on "Narrows" (that his wife Helena inherited from her father Jaques Cortelyou) to Middleton in Monmouth Co., NJ. They sold most of this land on the "Narrows" to Jaques and Tunis which are recorded in the Kings Co., Conveyances 1679 - 1736. Images 589-593 and 620. He also witnessed several deeds and purchases in Kings Co., with his HH mark such as 29 Apr 1724 land sale from Clas and Fransyntye Van Dyke to Joseph Hageman (Kings Co., Conveyances 1724- 1803 Vol 5. Images 7-8). Francyntje Hendrickson, wife of Claus Van Dyke is believed, to be the sister of Willem, Daniel and Hendrick Hendrickson who all settled in Monmouth Co., NJ at one time or another. The only other proof we have besides the 1708 land conveyance that Hendrick Hendrickson was married to a Tryinetje/Catherine Van Dyke was the baptism of a daughter Jannetje baptized in the Dutch Reformed Church of Brooklyn, NY 29 May 1705 (Brookly DRCR, p. 498 Bergen): "Janetje d/o Henrdick Hendrickze & Tryntje, Claas Van Dyke & Jannetje Van Dyke witnesses Johannes s/o Willem Hendrickson & Willemtze Lane, Stoffel Schar & Geesje Van Heckel, Antoni Rutgers & Antje Caros witnesses." There can be no doubt that this is our Hendrick as Claas Van Dyck, the husband of Hendrick's sister Francyntje Hendrickson, and Jannetje Van Dyck are listed as witnesses. Plus Willem Hendrickson, Hendrick's brother, and his wife Willemtze Lane had their son Johannes baptized at the same place on the same day. Around the time of the marriage of Hendrick Hendrickson and Helena Cortelyou in 1708, Helena wrote a document in which she stated that her son Jacques Denyse and her son-in-law, Hendrick Van Louwres, should take the administration of her personal estate pursuant to an agreement made between her and her third husband, Hendrick Hendrickson. She decrees that all her children shall have equal portion in her estate, including the heirs of her son Nicholas Van Brunt who was deceased, whose heirs were to have one equal share of her personal estate. It was dated 4 Apr 1708 and later notarized the 27 Oct 1726 by Helena with her personal mark which was "H" (Reminisces of New Ultrecht and Gowanus p. 39). In the Kings Co. NY Conveyances 1679-1736 Vol 3, pp 137-138 part of Jaques Cortelyou Sr's estate is conveyed to his daughter, "Helena Tunisse widow and relict of Denyse Tunisse", the 12 Sep 1707 by her brothers Jaques and Peter Cortelyou and their wives. This indicates that Helena Cortelyou the widow of Denyse Tunisse married Hendrick Hendrickson sometime after this date while our ancestor Hendrick Hendrickson Jr. was born 11 Nov 1706. And what about Hendrick's sister, Geesje Hendrickson, who is listed as being born as late as 1710 by some historians? She married Nicholas Van Brunt and according to his 1760 Will they had three older children, Cornelius, Trynetje and Jannetje. Since the earliest known birth date we have for any of Geesje and Nicholas's children is Antje/Enjeltie, who was Bapt. 23 Apr 1732, then we must assume that at the least the three older children were born before this date pushing the marriage date of Geesje and Nicholas to around 1726 if not earlier. Since most of these early Dutch did not marry until around age 21 this means that Geesje probably was not born any later than 1705 so she may have been the oldest child as she was probably the first child to get married. Geesje never named any of her children Helena plus none of the children of Hendrick Hendrickson, including Geesje, ever received any of Helena Cortelyou's estate which would not have been the case had she been their birth mother. She did however name her oldest daughter Trynetje which would have been expected if her mother were Tynetje Van Dyke the daughter of Achias/Agyas Janse Van Dyke. Hope this helps and thanks once again. Del Leavitt Research Director of the Henry Hendricks Family Org.
