Richard,
Yes, I know a small bit about the Kea's. Everything I learned I know from my great grandma who is 97 now. She even remembers Joab! Her husband was the second oldest son of Joab's son Josiah. Yes, John Jay and Flavius were brothers. I am not aware of Joab having a brother named Ferguson, but his father was Ferguson Kea and his mother Margaret Jackson. There is a wealth of information about the Jackson's on the internet. Her father's name was Benjamin I believe. Please contact me at
jessbell98@aol.com and we can compare notes.
