So it seems like a good time to provide some help in getting started. Type the surname you're searching for in the little box. And if it shows up in the list below, it will be associated with a Clan. In this case, there are four associated Clans. Click on any of the Clan names - and you will be taken to that Clan area.
Spelling is less important than sound.
People 100 or more years ago weren't as fanatical about spelling as we are today. Also, don't be surprised if the name you're searching isn't associated with a Clan. The majority of Scottish surnames are NOT associated with a Clan. If you're in the Clan Smith area, you'll see Smiths on the Net, Clan Smith Contacts and Clan Smith Message Board. There are useful articles here for the beginner.
