It’s been awhile since I read Wolf Hall, but if I remember the plot, it was about a guy named Thomas whose rival Thomas didn’t like him so allied with Thomas, who was friends with William, and William asked Thomas to tell William to betray John, because John thought William was friends with John, and Thomas decided to go ahead and do it.
Wasn’t there also a second “Tony Soprano” and the family identified them by whose nephew they were? It’s been a while since I watched it.
In The Last Temptation of Christ, there’s Mary (mother of Jesus), Mary (Magdelene) and Mary (sister of Lazarus).
In Monk…
Mr. Monk and the Big Game. Monk was an assistant coach and the team had two players named Emily. There were several comments about that.
Mr. Monk and the Three Julies. There were two people murdered named Julie Teeger. The daughter of one of the main characters is also Julie Teeger. So, there were three people named Julie Teeger.
There’s another example in your username…
“Sarah Connor?”
“Yes?”
BLAM! BLAM, BLAM, BLAM!
“Shit, wrong one!”
Technically, at the start of The Terminator there were three Sarah Connors, all essential to the plot even though two were not on camera. By the end of the movie there was one, essential to the future of all humanity.
Reading my mind, again?
You got Ninja’d! Your only hope is to travel back in time and kill all the @burpo_the_wonder_mutt’s in the phone book before they can post ahead of you.
Woah, shit!
Thankfully, my number’s unlisted!
I think you said it better than me.
Also John the Baptist and John the Apostle.
I, Claudius was a nightmare of similar names. Graves gave them all separate names, some of which he invented to keep them distinct.
Gaius Julius Caesar Augustus (Augustus)
Tiberius Julius Caesar Augustus (Tiberius)
Gaius Caesar Augustus Germanicus (Caligula)
Tiberius Claudius Nero Germanicus (Claudius)
Tiberius Claudius Caesar Britannicus (Britannicus)
Nero Claudius Caesar Augustus Germanicus (Nero)
Agrippina the Elder (Agrippina)
Julia Agrippina the Younger (‘Agrippinila’)
Julia Drusilla (Drusilla)
and so on. You need a score table to keep track of them.
Tony B was Tony Soprano’s cousin, so I wonder if that’s who you’re thinking of. I don’t recall a second Tony Soprano, but it’s been equally long since I’ve watched it.
“Hi, I’m Larry. This is my brother Darryl, and this is my other brother Darryl.”
Yeah, I think you’re right. The confusion was when people called for “Tony” they’d have to say “Tony Uncle Junior” or the other one. I thought it was because there were two Tony Sopranos. Never mind me.
Though in the same vein, does the wedding reception in Goodfellas count, as it’s filled with Peters, Pauls and all their girlfriends and daughters named Marie?
Joey Tribbiani has how many sisters named Gina? 
Karen in Goodfellas:
It was like he had two families. The first time I was introduced to all of them at once, it was crazy. Paulie and his brothers had lots of sons and nephews. And almost all of them were named Peter or Paul. It was unbelievable. There must have been two dozen Peters and Pauls at the wedding. Plus, they were all married to girls named Marie. And they named all their daughters Marie. By the time I finished meeting everybody, I thought I was drunk.
The movie Kelly’s Heroes had Big Joe (Telly Savalas) and Little Joe (Stuart Margolin).
Just thought of another obvious one: Heathers.
Dupont and Dupond. I always liked how one would say something like “with a P as in psychology or pterodactyl”
A Song of Ice and Fire has of course multi-generational names, but as contemporaries the Frey family has a very large tree with multiple Walders. Including two named Big Walder and Little Walder (the big one is smaller).
In the Book of the New Sun, Severian travels with a kid named Severian. He is not a safe travelling companion.
