Roy,
Since my last reply I have found the book you sited: "The Birth, Marriage, and Death Register, Church Records and Epitaphs of Lancaster, Mass: 1643-1850" and in that on page 388 it does list the Chocksett Church baptism of Jane Rogers Judevine 16 Apr 1769 to Wm Judevine.

Apparently this is not in the online database search that Ancestry has, but it is in the records. I also found online the book that shows the birth of William Judevine in 1738. Thank you very much. I would like to hear your thoughts on the other points I mention.
