Excellent detective work, Frances. So it looks as though Joney b 1727 was born illegitimately to a John McDonald and Eleanor Harrison, then grew up using her stepfather's name of Crebbin, and then married John Gick as Joney McDonald ?
I wonder if John McDonald was the same man as the one who married Eleanor Watterson, in which case, Joney would have had lots of half siblings of Crebbins and McDonalds.
Well, Michael, after you've sorted out all your Gicks, there's lots of scope for research into these half-blood connections to keep you going for years !
