You have asked, "I assume the names mentioned, along with the percentages, were for living people?"
I am not entirely sure about this. The recipient of the largest share, Hendrick Van Sicklen, is a mystery to me if he was alive when the Hennenlotter presentation was made.His share is nearly twice as large as the next most share designee, John Johnston; and three times as large as the next two after Johnston, Fitzgerald and Stillwell; six times as large as Mary Austin, Matthew Lawson, Court Van Sicklen and Phebe Remer.
Because of this, I suspect that the Hendrick share is that of Hendrick(5), but that Hennenlotter was unable to find descendants to whom to further parcel out that share.I don't have anything further on this Hendrick(5) Van Sicklen, except that he was born 15 March 1767 [Bible], baptized 29 March 1767, recorded Flatlands RDC [Flds 1:15]. Obviously, he was not alive in 1912.IF this interpretation is correct, it suggests that Hennenlotter could not rule out that Hendrick(5) married and had children and therefore held that share out.
Henry(5) Van Sicklen's nephew, Henry(6) Van Sicklen, son of Court(5) Van Sicklen and Catherine Johnson, specifically calls his Uncle Hendrick, "Henry," but does not mention him further.This anglicizing might have thrown Hennenlotter and students of the family (including me) off the trail. Henry(6) Van Sicklen was born 14 December 1804, Pleasant Valley, Dutchess County, New York, died in Gravesend, Kings County, Long Island on 17 December 1886. As far as I have been able to ascertain, this Henry^6 did not have children who lived to adulthood, by either of his two wives.
Have you any information on Hendrick(5) Van Sicklen, son of Cornelius(4) Van Sicklen and Femmetje Vanderveer?
