Virgins?
I did not know that! (Obviously.)
Damn, I hope y’all are enjoying this thread as much as I am.
Bifocals
Ice cream
Computers
Salisbury steak was named for a physician.
Might as well give it to you. Looks like you over analyzed it. They’re all named after men (not necessarily noblemen).
Well how 'bout that. I knew the other two and just figured Salisbury (with a name like that) must also be some obscure nobleman.
Still waiting on this one:
Epileptics
I was going to say authors. At least Caesar and Dostoevsky have written things. Not sure about Weaving.
Well, that’s certainly a better answer.
Yep.
Um… all invented by people living on the east coast of the US? All helpful for when you’ve got tonsillitis? All contain the letter ‘C’? All are delicious when covered with hot fudge*?
*(Except for computers and bifocals.)
You’re on the right track with one of these, but it’s more specific.
Well the first two are pretty much invented by quakers. I don’t know what computers have to do with it, though.
Kinda sorta all from Philadelphia. Sorta.
Well, if you’re trying to get that they were all invented in Philadelphia, I’m pretty sure you’re going to run into trouble with “computers.” IIRC, the first “modern” computer was built in the '40s at either MIT or Harvard. Of course, there are varying degrees of modernity, so by some definitions the “computer” was invented in ancient Egypt and by other definitions it was invented in 2007 when Apple came out with Leopard. 
I’ll totally give you ice cream and bifocals though. Both are definitely Philadelphia creations.
Here’s another:
Patrick Stewart
Laurence Fishburne
Orson Welles
(HINT: It’s not just that they’re actors.)
Franklin wasn’t a Quaker, he was a Congregationalist.
Whaddya mean, “kinda”!?!?!? You dissing the ENIAC?
I don’t agree about ice cream. I think it was brought to the US from England.
Yes, maybe. At least, all were unmarried and had no longterm sweetie pookumses.
How about:
Henry Ford
Warren G. Harding
Thomas Edison
Played Othello?
Not according to Philadelphians!
Okay, okay, uncle. I withdraw the troika. 
I don’t know about Freud, but I think there was something hinky about Poe and Liston’s deaths.
