The Honourable Miss Lueretia MacTab. A poor Scotch relative of Emily Worthington on her deceased mothers side, and of the noble blood of the MacTabs. She lived on the Worthingtons, always snubbing them for not appreciating the honour of such a noble hanger-on, and always committing the most ludicrous mistakes from her extravagant vanity and family pride. (George Colman: The Poor Gentleman.)
