Hello, Doug: :-)
We have your e-mail. As I explained earlier today, the Chief is currently away from the office. He will call you later this week.
When a Clan has been dormant as Clan MacTavish has for 200+ years, there are all types of people who feel they have the "correct" answer. I have seen your posts here, on the Gunn Board, in the e-mail - all in the last 3 days - you may get numerous answers and none of them may be correct, but rather different people's personal "opinions".
So that there is no confusion relative to the connection between MacCamish and MacTavish from our Clan's perspective, perhaps the best person to explain it is the Chief of Clan Mactavish.
On our official web site at http://www.mactavish.org
there is an enormous amount of information relative to Clan MacTavish, septs, connected names, our history, the matriculation of our Chief, etc. Much of this information has been research by our Chief in the last 53 years (with help of his Clan members in recent years) and brought to light since his matriculation in 1997. There is enough to provide one with several hours of reading. The information may provide you with answer to your questions.
There is an excellent article on "septs" by Sir Crispin Agnew at http://www.mactamhais.liquidweb.com/names1.htm
Sir Crispin is a member of the Lyon Court in Edinburgh and his article gives a good explanation of the word "sept", which is very confusing to most Americans.
MacCamish is not a sept of MacTavish, but I will leave that to your discussion with the Chief. :-)
Another item for you to use in your research is Prof George Black's "Surnames of Scotland" (recommended by the National Archives of Scotland as a book for use in researching Scottish surnames). Be sure to read the Introduction to get an understanding of "variant spellings" of names and naming practices. Also, be sure to read Pg 554 â€“ â€œMACOMISH, MACCOMISH â€“ G. Mac Thomais, â€˜son of Thomasâ€™ â€¦Variant spellings and information on Mâ€™Comash, Mâ€™Hamish, Makcomius, McKomash â€¦â€
I hope this helps.
