Hi Marge, You asked specifically about sources, so I'll try to answer that. Ethel mentioned the First Reformed Church of Tarrytown, and you called it the Old Dutch Church of Sleepy Hollow. Actually it is the same. The records were originally published by David Cole in 1901, and titled: "First Record Book Of The 'Old Dutch Church of Sleepy Hollow' Organized In 1697 And Now The First Reformed Church Of Tarrytown, New York" An original translation of its brief historical matter, and a copy, faithful to the letter, of every personal and local name, of its four registers of members, consistorymen, baptisms, and marriages, from its organization to 1791, by Rev. David Cole, D.D., Yonkers, N. Y., Published by The Yonkers Historical and Library Association, 1901. The records are available on-line here: http://freepages.genealogy.rootsweb.com/~vantasselfamilyhistoryhomepage/Dutchchurchhomepage.html The Records of the Reformed Dutch Church in New Amsterdam and New York (Vol. I, Marriages, 1890; Vol. II, Baptisms, 1639-1730, 1901; and, Vol. III, Baptisms, 1731-1800, 1902) were published by the New York Genealogical and Biographical Society, and are available on-line here: http://olivetreegenealogy.com/nn/ Start by clicking on Church Records (B, D, M), but there is a whole lot more (Ships Lists, naming patterns, customs, etc, etc). The Bergen Church is in northern New Jersey, and the records were published thusly: Versteeg, Dingman & Thomas E. Vermilye, Jr., BERGEN RECORDS - RECORDS OF THE REFORMED PROTESTANT DUTCH CHURCH OF BERGEN IN NEW JERSEY 1666 to 1788 Three books in one; originally published in the Year Books of the Holland Society of New York; baptisms, marriages, and deaths from the oldest church in New Jersey; some narrative history as well. (1913-5), Reprinted 2003, Vol. I, 124 pp.; Vol. II; 85 pp.; Vol. III; 91 pp., The Hackensack Church records are from: RECORDS OF THE REFORMED DUTCH CHURCH OF HACKENSACK, N.J. (1686 - 1800) From Collections of the Holland Society of New York, Volume I, Part I. Registers of Members, Marriages, Baptisms and the Consistories (See publication #21 for later records.) (1891), Reprinted 1998, 349 pp., index, cloth Both are available for purchase at: http://www.bergenhistoricbooks.com/ChurchRecords.html but many Dutch-Colonies list members have the books, and would be glad to do look-ups. I checked to see if there was a specific article on the above families that was published in the NYG&B Record, but apparently not. There is one article (1985) on the Van Blarcoms but it does not deal directly with your line (and, would not yet be available on their e-library website). It is titled "Gerrit Lubbertsen Descendants of Jamaica, L.I." and appears in Volume 116, pp 154-163 and pp 202-210 (Oct 1985). Information on the Buys family is apparently included in Vol. III of Frank Doherty's "Settlers of the Beekman Patent" on pages 103-139. I am not familiar with the "MacKenzie Surname Index" so perhaps someone else can help you with that. One addition to the information provided by Ethel: Tryntje Hendricks Oosterom, the wife of Ariaen Pietersz Buys, was baptized at the New Amsterdam Reformed Dutch Church on 16 Aug 1654, as published in Volume II, page 37 of the series mentioned above (and also on-line at The Olive Tree). "Hendrick Janszen; Tryntie; Jan Corneliszen Buys, Gysbert Lubbertszen, Aeltje Schryvers" Tryntje's parents had married at the same church [Banns] 4 Dec 1652, from Volume I, p 18, of the published records: Hendrick Janszen, Van Schalchwyck in't Stecht Uytrecht, en Tryntje Lubberts, Van't Fort Orangien. Last but NOT least is information on the Hoppe Family: Andries Willemszen Hoppe(n) of New Amsterdam 1651-1658; The First Six Generations; Compiled by: Maria Jean Hopper http://www.reetree.com/html/my_book.html The above should get you started, and we'll look forward to the rest.
