Philip Morris is a tobacco company. A lot of people have made this connection. But no, no relation AFAIK.

Thats the name of the Prison/town the Breakers were held in the Dark Tower.
Two possible sources for revtim’s name.
I think it’s probably from Reverend Tim Flotsky in Soap.
It could also be Reverend Timothy Lovejoy from The Simpsons. I don’t think so, because he’s usually called ‘Reverend Lovejoy’ but the former was called ‘Reverend Tim.’
I thought that a-ha was in a group called the Americans or Young Americans or somesuch. I think his music precedes the popgroup by that name by some years.
Jadis is a witch in the Chronicles of Narnia (she’s scared of Aslan). I learned this recently as I’ve been reading the series to my kids. Her location is even listed as Charn, her home city or world (I forget which).

Mycroft H. is a reference to Sherlock Holmes’ older brother, reputedly smarter than he was.
