There is not enough information provided to be absolutely sure, but the Dr Silas Roll you mention appears to be son of: Matthias Roll and Mary Rutan, child of John Roll & Mary Van Winkle, child of John Roll & Elizabeth Sickles, child of Jan Mangalese & Volkie Janse Adriansen Israel Roll is also a child of Mattias Roll and Mary Rutan The Mathias Roll you have in your note is apparently the one indicated above, except that you show a child named Isaac which I do not show. All other children's names match. All this info is in the New Jersey Rolls, which should be ready for you in about a week. Hansel
