Maybe J K Rowling had heard of yours - the Weasley family live at The Burrows and had six children.
My Latin Master (yes, it was a grammar school !) was Mr Riley.
He was already ancient when I was 11 years old (very nearly 50 years ago); but was still going strong when I saw him at the funeral of my old Headmaster a few years ago.
Mr Riley used to growl when he spoke (but, more likely, yelled !), and he spoke with a slur, as well; so it wasn't until I saw it written down that I realised that the correct spellings for the declension of 'bellum' (war) were NOT blum, blum, blum; blee, blow, blow; blah, blah, blah; blorum, bleece, bleece.

Coincidentally that quotation came up on University Challenge, in a question about paradoxes.
A philosopher from Crete said "Cretans always lie".
Aesop agreed: "A liar will not be believed, even when he speaks the truth".
Aha! Κρητικοί βρίσκονται πάντα. I haven't noticed many liars but the truth is sometimes bent to serve their purpose!
