Well, I;v done many many searches, almost entirely online for tartans associated to these names.
McGurk, I;ve found a few week connections to some clan names, but non that i'd associated myself to.
Tulloch, I;ve done less searching for, but but its raised some questions as it is a family name, but might also be a place. However, I dont think either have their own tartan.

I doubt anyone here would know of any tartans off the top of their heads, but could anyone suggest anywhere I might look that I might not have tried yet?
(I;ve tried tartan ferret and other tartan finders and catalogues)

Any advice would be greatly apreciated!
