sold father's property (Castello Plan notes)

NO·9
This house, which stood on the exact site of No. 21 Pearl Street, was built between July, 1645, and July, 1647, by Gillis Pietersen van der Gouw, master carpenter.-Cal. Hist. MSS., Dutch, 38. At the period of the Plan, it was owned by Isaac Grevenraet.
His sons, Andries and Henry, sold the property, in May, 1687, to Mme. Aeltje Schepmoes,[I] widow of Jan Evertsen Keteltas.-Liber Deeds, XIII: 301. By that time, a much better house probably had replaced this one, for the widow paid 7,700 guilders for the property. In July, following, she married Johannes van Giesen, of Utrecht.-M arriages in Ref. Dutch Ch., 62; ante-nuptial contract, Liber Deeds, XXV: 46. For Grevenraet, see Block C, No. 12.

Story of piracy, Andrew Gravenrod's sloop (The Katherine (?)): Pirates of Maryland: Plunder and High Adventure in the Chesapeake Bay by Mark Donnelly, Mark P. Donnelly, Daniel Diehl, Daniel Diehl Stackpole Books, May 14, 2014

In this book we read of Captain Kidd and his partner (Turner) who used Andrew's vessel for piracy purposes:

Gravenrod's Sloop detained on the Severn River in Maryland (1699) This may have been the sloop Katherine of which Andrew was the captain.

We read in the Proceedings of the Council of Maryland, 1636-1770‬, Volume 25 on page 77 of the detention of Andrew (Andries) along with the pirate Turner. (Turner was held and Grevenraedt was released.

Proceedings, July 1699

It would be worth investigation to see if this Grevenraedt was one of the sea captains involved with the transportation of slaves back from the West Indies. We read in In the Shadow of Slavery p.29 " Between the 1670s and 1690s, the Philipse and Van Horne clans, two of the New York colony's elite families, traded with pirates for slaves from Madagascar...." Note that the Grevenraedts and Van Hornes were linked by marriage through the Meyer family.
Additionally, Andries was married to a Van Brugh/van Rensselaer, arguably the most powerful family on the upper Hudson.

Johannes Van Hoorn who was a contemporary, married Catherine Meyer; and Catherine Meyer's grandmother was a Gravenraedt. Keeping that pedigree in mind and discovering, too, that our Andries Graevenraedt (aka Gravenrod) is documented to have met a group of pirates on the way back from Madagascar, we see a connection That is, there is a pattern or circumstances that would suggest that Andries might have acted as an agent for the Van Hoorn merchant interests that included slave trade.

Perhaps Andries Grevenrod wasn't all that innocent of dealing with pirates after all. :);)

I'd like to see the sources for In the Shadow of Slavery p.29 They are: Kruger: Born to Run, 78-79 Foote: Black Life, 32-37 Graham Hodges: Root and Branch, 38-40

Andrie's Grevenraet also had impeccable credentials through his wif'e's family. His father-in-law was one of the most honored men in old New Amsterdam. ]
