I have copy of a page from the Thurso register that has a William Manson of Pennyland near Thurso witness to the proclamation of marriage of my 3x great grandfather William Shearer in 14 Nov 1795. WS was overseer to the laird Capt James Sinclair of Holburnhead . So I presume WM is a gentleman of standing in the community.
On the same page of proclamations one witness to marriage of Alex Reid , weaver, and Mary Munro is Mr John Manson , saddler and another entry has a Mr Manson of what looks like Borrowston as witness to marriage of Alic Cormack, shoemaker in Forse and Jean Mckay of Borrowston.
