There's the possibility of Frederic, too. It sounds like Roderick, and Frederic and Mabel were the main characters in "Pirates of Penzance." (Mabel's father in that play was named General Stanley, too).

It's one of the reasons I want this wiki to go back to saying the show happened in 2012. The character Frederic was born on a leap-year, on the 29th of February. Mabel made a leap-year reference in "The Inconveniencing." If they were born on a leap year (2000) then this theory works.
