Title: History of Luguen of Strathearn and his children
Description: If you are interested in the family name and history, there are only 3 copies of this book still available at  world cat libraries. I have 4 fifths of it copied. The first person to used the name of Gass was Galfriddus of Gaisk in abt 1228 in Perth.  Most of the book is the process and specifics of the author's findings with the assistance of a friend.  I found it a great read and due to it, I have been able to go much further into this Pict tribal originations.
