prohibited tartans

[M. A. C. Newsome]

Charles McKerrell of Hillhouse is an absolute gentleman, but he is painfully shy. Madam McKerrell, who is a charming lady, usually deals with all telephone conversations, hence she is usually the first point of contact for Clan McKerrell matters, including permission to wear the McKerrell tartan.

Good to know, thanks. That explains the reason for my previous confusion. :-)
