Séan O'Smeara:
Thanks for clearing that up!
An old Dublin Lady, friend of my mother's (Circa 1960) always used "Me Auld Segotia" as a term of endearment and your explanation of Auld Flower evolving into Auld Segotia makes perfect sense!
I love the exchange of abundant theories ...
I'm a Dubliner by birth and education, however, left (sadly) in 1976 for further shores.
I have never heard the word Dub used as Dublin slang for toilet ("Rub-a-DubDub. 3 Men in a tub"???????
