A good place to start when looking for information on the 1st 2 or 3 generations of Mayflower passengers is Caleb Johnson's Web site: http://members.aol.com/calebj/mayflower.html It has reliable information and provides some sources. Regarding Degory Priest, Caleb says he & wife Sarah (Allerton) Vincent had 2 daughters born in Leyden, Holland: Mary, b. ca. 1613 and Sarah, b. ca. 1615. Both married. More in-depth information on Degory's descendants can be found in the Mayflower Society's "Silver Book" (a series of 5-generation studies on MF descendants) for the Priest line. I have one of the Silver Books that includes the descendants of both Edward Winslow and of John Billington (his granddaughter Elizabeth was the 2nd wife of my paternal ancestor Richard Bullock.) I don't recall if there are any Mendon names in those lines. My only known MF line is from John & Elizabeth (Tilley) Howland. John has a lot of descendants, so there will be more than one Silver Book with his descendants. I know of one that traces his daughter Desire's line, and there might be one other. (?) However there is none for my ancestor Lydia Howland. There is another series, the "Pink Books" that traces the lines for 4 generations, but I believe they don't always have the most up-to-date information available. Jim Bullock Littleton, CO
