Scottish mummies found

Certainly that's true. It is an extremely unusual point of note so see mummification occuring in Britain - especailly as the method also differes frmo the Egyptian. Instead of filling the disembowelled body with salt, naptha, oils and incense etc, you have peat acides being utilised to do the trick.

That suggests either the independent discovery of mummification as a method for processing the dead - or else that Egyptian ideas on mummification were being actively spread.
