Hello Claude. I remember seeing somewhere that "Jonnet" was the wife of the "John Burns" that bought the land on Rocky Creek from Old John "B" Burns. I'll try to find where I got this. I could certainly be wrong. Anything to show Jonnett was the wife of our John "B" Burns?
In any case both Johns (and Laird) could share a maternal "Laird" ancestor IF they were related (Cousins)
