What I like about this type of discussion is that the term "Clan" is never discussed or defined. Many members of a Clan may not have had the same name as the Clan Chief and may not be related by blood. Look at the numbers ofsept associated with many clans.

If you have Scottish ancestry there is a chance that you are related to all the Scottish Clans. People moved across the country during wars and for other reasons. It is well known that during these travels that young males would never talk to or pay any attention to the local ladies. Since they never paid any attention they could never have left unexpected gifts.
