The Eldon Van Scoyoc you refer to is listed in Volume III, page 595 and Volume I, page 518. I do not have Volume I, but I was able to glean a little information from the information I copied from it.Eldon Van Scoyoc, Sr's code number is V-1-2-2-5-7.It appears his ancestry is: Adrian (Aert) Van Schaick, b. ca 1580 I-1 Cornelis Aertsen Van Schaick (Vol 1, p. 42), b. ca 1610 II-1-2Arie (Adrian) Cornelissen Van Schaick (Vol 1, p. 44), bp. July 9, 1642, New Amsterdam III-1-2-2 Iden (Eden) Van Schaick (Scoy) (Vol 1, p. 46), bp. Oct. 28, 1665, New York IV-1-2-2-5 Aaron (Adrian) Van Schaick (Scoy) (Vol 1, p. 46), bp. Dec. 25, 1692 V-1-2-2-5-7 Enoch Van Scoyoc, Sr. b. 1760. I don't know for sure if this is correct because I don't have Volume 1.One fact that makes me question the accuracy is that this schedule indicates Aaron was 68 years old when his son, Enoch was born.I'm sure this is possible, but it does seem unusual.
