As a small contribution, I have a file which contains my understanding of the lineage of the chief of Clan McQueen, which can be downloaded from http://www.mngt.waikato.ac.nz/bmcqueen/WEBDOCS/mcqueen

The current chief, descended from the Corrybrough McQueens, is John Alexander McQueen, who is a resident of New Zealand. I met John a few years ago, and he is an extremely nice man, and attended a gathering of one
branch of McQueen families in New Zealand earlier this year in his official capacity as clan chief.

Hope you find it interesting.... I would welcome any comments off-list.
