Hi Tattie Bogle. I agree with your pronunciation but wonder if it would be 'explained ' as Mac phrr son. It's my eldest sisters married name and she cringes when called Mac fear son though the 'local' (Blairgowrie) sound would be more like Mac ferrson.

BTW I do appreciate correct pronunciation and spelling of my name, having gone from a McGregor to an English RICHINGS it is irritating to have a 'T' placed before the C! The voice recognition technology at hotel bookings continually refuses to accept my name and patches me through to a 'live' operator!!!
Hazel.
