I,too, am a descendant of Benjamin F. Prentice married to Laura Ann Willson. Their second child, Laura Imogene, was my mother's mother i.e.my grandmother, who married Walter Luke in Nebraska. Laura's brothers and sisters were as follows: Ruth, John Chester, Will, Paul, Howard, Adelaine, Robbie, and Dorothy. All born in Blue Hill, Nebraska. I also have family pictures of the family in Nebraska.
Adelaine is still alive and in contact with my mother. I have the entire Prentice genealogy compiled by Ione Faye Prentice Jordon, daughter of John Chester. I have not taken the time to verify her records, but they do go back to England to the first Prentice (Valentine) who married Alice (?)They seem fairly complete and would be happy to share. Dordie
