Were the brake brothers educated at licensed victuallers school in slough?

There's no record or evidence suggesting that the Brake brothers (assuming you're referring to a specific set of brothers) attended a "Licensed Victuallers School in Slough." Licensed victuallers schools were institutions that trained people to run pubs (public houses), but there's no known school with that exact name and location. It's possible the name is incorrect, or the story is inaccurate.
