This same excerpt is at Long Island Genealogy , where it's followed by a long Flewelling gedcom.I asked the LI Genealogy guy where this gedcom came from, and he said he didn't remember where he got it.I checked around and I think the "Keeler-Wood genealogy" referred to is Ancestors of Evelyn Wood Keeler, wife of Willard Underhill Taylor, compiled for their children, Mary Morgan Taylor, Willard Underhill Taylor, Jr. [and] Annette Evelyn Taylor, by Josephine C. Frost (Mrs. Samuel Knapp Frost)(1939).

Incorporated Districts, Boroughs, and Townships in the County of Philadelphia, 1854, by Rudolph J. Walther , gives the date of the Passyunk grant as 1 Jan 1667/68.
Peter Rose, History of Long Island from its Earliest Settlement to the Present Time, (1902), lists Caleb Carman, Robert Ashman, and Thomas Wellin as freeholders at Jamaica in 1660.
