Hi again Chris, > Dr. Kerfbyl, a graduate of Leyden University, was in NY by 23 Apr 1681, when > he witnessed a baptism. He performed the high-profile autopsy of NY Governor > Henry Slaughter, who died suspiciously in Jul 1691. Kerfbyl was a founding > elder of Trinity Church, and died about 1704. Don't you mean he was a founding elder of Reformed Dutch Church of New York? In The Charter of the Reformed Protestant Dutch Church of New York, bearing the date of 8 May 1696, the following were mentioned: The form in which the names of the Elders and Deacons appear in the text is doubtless due to the English scribe by whom the Charter was drawn up. In the Minutes of the Consistory, which are in the handwriting of Domine Selyns, they are as follows: Elders, Nicolaes Bayard, Stephanus van Cortlant, Willem Beeckman, Johannes Kerfbyl: Deacons, Isaacg de Foreest, Johannes de Peyster, Jacobus Kip, Isaacg de Riemer. See: http://www.upword.com/collegiate/charter.html Out of curiosity, I went on a hunt to find the parents of Dr. Johannes Kerfbyl, and find that he was baptized in Amsterdam on 7 Nov 1634 at the Nieuwe kerk, [DTB 41/345], the son of Cornelis Jans Kerfbyl and his wife Marritje Sijmons. This couple also baptized a son Sijmon on 11 Nov 1642 at the Nieuwe kerk [DTB 42/331] in Amsterdam, and he married Anna Valentina Meijert circa 1669. It was this Simon who witnessed the baptism, by proxy, of Anna Valentina Kerfbyl at the New York Reformed Dutch Church on 29 Sep 1706: 29 Sept 1706; Johannes Kerfbyl, Margrietje Provoost; Anna Valentina; Symon Kerfbyl in Amsterdam, Catharina Kerfbyl, Wed. The other sponsor of course was the paternal grandmother, Catharina Rugh. Regards, Pam Sears
