Thanks for the response. I got concerned when I didn't get a response to my registration and assumed I was doing something wrong. Obviously, I cannot read most of the MacTavish material without being registered.
While you have seen a barrage over the last few days, this is not a new question. As I mentioned, our late McCamish genealogist, E.C. McAmis (the earliest written forms of our family name in North America are "McCamish" as noted in E.C.'s books) was absolutely sure that we are of Clan Gunn. However, I have had several emails from other researchers pointing me to the MacTavish site and that site lists MacCamish as a connected name or sept. I'm just trying to keep an open mind.
All we really know is that there were McCamishes in Pennsylvania (English colony of) in about 1725 and that three McCamish brothers fought in the American Revolution, having been somewhere in the colonies for a while. No one, not even E.C. for all his work, has ever found a ship list or anything else to trace us over the pond. The Australian branch of the family may have some connections. There is a record of a McCamish being excommunicated in Northern Ireland and there are some records of McCamishes living in southwestern Scotland - none of which helps us at all.
Thanks again, Doug
