My difficulty with this line of reasoning (and I've had past exchanges with Phillip) is that we don't start with what we know (i.e., Gaddey/-ie--y), but with what we speculate--that there is some connection with Gad. (Which, by the way, means spear or spearhead in Anglo-Saxon, so is pike the fish in Danish or the "spear"?) I would not suggest we get hung up on spelling, but that we narrowly focus on what we have, keeping in mind other possibilities, but be very loath to latch onto them without solid basis (which was what mislead me for so long with Gaddy-Geddy) .Earliest Gaddy I've seen is Capt John, c1719. around NE NC. We can find "Gaddy-looking" names all over the place. (How about Hebrew tribe of Gad?) But I'm not sure how useful that is in our own family research. By the way, I've never seen Gad as an accepted Scottish clan, but I can always learn. Cheers.
