The surname MacKenzie is the letter yogh's equivalent to "ye olde": printing presses imported from mainland Europe didn't have movable type pieces for certain Old English letters, so those letters would just get replaced with the most similar-looking letter that did have type. So, Þ became Y, and Ȝ became Z. MacKenȝie with a yogh was pronounced like "MacKeng-yee", which is why in Scotland today, unlike the rest of the world, the surname MacKenzie is pronounced "MacKen-yee". Elsewhere, people started saying it how it was spelled.
