"Centenery of Catholicity in Kentucky" by Hon Ben J. Webb, copyrighted 1884. reprinted by McDowell Publicationswill be very helpful to you.The body of the book is about that large group of Marylanders who made a pact to settle in KY as a group.They did settle along Pottinger's Creek and in what is now Nelson County. Much of Webb's research came from the records of Parish Priests. You may find it in the genealogy sections of some libraries. If you can't find it in the library, e-mail me at firstname.lastname@example.org and I will send you the address of McDowell Publications. I can't remember specifically if the Cecils were included, but if they came with this group, they will be.
