Here it is for example in an Australian newspaper ad from 1844: https://trove.nla.gov.au/newspaper/article/31742822

I'm sure I could find more examples, but I think two will sufface.
I don't know man, maybe it's because fixing this one completely inconsequential bug faces so much backlash for no particular reason other than "change bad"?
And well done with using an example from a book series where the only Asian character is named Cho Chang and where there are elves with long noses in charge of the "central bank". That really works in your favour, you totally owned me [pun intended] with that one!
isn't an example of the phrase "master bedroom".
I am also skeptical of "school house and master's bedroom". The main cottage has "four large bed rooms". Why would the "master bedroom", if it is meant to be read as it is today, be listed after the list of detached outbuildings?
