For whatever it's worth, enter the following item in the "loo"

etymological sweepstakes. It's from Punch, 7 November 1896, pg. 219, col. 2:

"The Chateau of Loo," where the two queens were recently staying, sounds

uncommonly like a house of cards. Unless "Loo" is short for "LOUISA," and if

so, who is LOUISA at whose chateau the two queens were staying? By the way,

asks the quiet gamble singing--

"Loo! Loo!

I love you!"

is there anywhere about a "Chateau of Unlimited Loo"?
