Hello Thomas. I have read through this compilation [terrific work, by the way], and see that you have a Jacob Jones married to Hannah Corey as possibly being linked into this family.
My own research into another Jones family [originally Schantz, who came to N.B. with the Steeves, Lutes, Trites, etc gang], has this Jacob Jones as son of Henry Jones and Christenah Somers. In the 1851 and 1861 census records, he is living in Salisbury parish, Westmorland county [1851 is with his wife Hannah; 1861 is a widower with his son Jacob Calvin]
If you have any information to offer to indicate that this Jacob is associated with your Zebulon Jones folks, rather than how I currently have him with my Charles Jones [aka Carl Schantz] group, please let me know. I'd be happy to send you a copy of what I have, if you'd like.
