Hi Donna and Wiinnarae,
If you look at my message dated Tuesday, 20 May 2008, at 12:15 p.m. (next below this I think if your computer displays the same as mine) I have put my readings from actual images (on Ancedstry) of the 1881 census entries which include Catharine Quirk and Margaret Quayle. The are both domestic servants in Derby Square and the name George Clague does occur, but they are not all in the same household at the time of the census. There's nothing to say there wasn't any movement sometime afterwards, though.
