Is there a website to help translate Gaelic patronymics?

Question

Im researching my Sutherland (Scotland) ancestors and have come across a couple of aliases I want to decipher. I did once find a site that explained how to work it out but lost it. It was nice and easy to follow!

The aliases are

Roderick Morison alias MACUILAMMACRORY

Mary Mackay alias ERUCALISTERMACUILAMMACRORY

Donald Morison alias RUADAIDH A'SHEARRABHAG

Answer 1

This is an Irish/Gaelic site but it might help a little.
