Mr Mc Bride in Busman's Honeymoon has a Scottish name but is not mean and avaricious. See the money-lenders in The Unpleasantness at the Bellona Club - they too have Scottish names. I'm afraid that the trope being used here is "Jewish money-lender hiding behind a Scottish name". However, I find Mr Mc Bride the funniest and most appealing character in the book.
