Mr Flemming
From BRGS Wiki
Mr. Flemming is a Scottish History teacher who likes to use the History textbooks and make you look and write about sources. He knows the origins of many surnames from places in Britain (although, it is unlikely he knows exactly where the names are from but he can say if it is Scotland, England or Wales) e.g. Smith is from England and was given to blacksmiths and goldsmiths (names beginning with Mc/Mac (son of) are from Scotland). He covered for Mrs Grehan when she went on maternity leave.
