How’s the Munster Koach running? 
Did you ever try to get a passport just using the name P? It is, or at least used to be, possible. The name on my birth certificate is not the same as the one on my passport. The only thing I had to do was get two people who knew me under both names to swear I was the same person. As it happened, the only two people who did were my parents, since my father changed his name (informally, not legally) before I started school. My father died five years later; I don’t know what I would have done then.
Your story reminds me of physicist Murray Gellmann, who changed his name to Gell-Mann. His kids must love him for that.
And my family changed Fuchs to Fox - partly due to the similarity in words, partly because after WWI and WWII they didn’t want their kids to face anti-German sentiment (which was fine when they were in very German communities in Minnesota, but turned out to be a thing when they moved to the Twin Cities).
I once met a guy whose last name was Frankenstein. He said his wife not only declined to take the name but insisted that their children have her surname. “It was an executive decision,” he said with some amusement.
And right after that, “And the really ironic thing is, I’m a doctor.” 
“No really, it’s pronounced Frohnkensteen.”
I know a lady who married a man with the surname Hummer. She took his name as a hyphenated addition to her own. Not the choice I would have made. What lady who is not a sex worker wants to be known as Susy Hummer?
I’m okay with my 10-letter name Nottingham, but my nephew shortened it all the way to No, like James Bond’s doctor.
I think if my name was merely odd, I’d leave it alone. My big brother went to high school with a cute girl named Fraundorfer, and he laughed when she was introduced to her. He could see right then, he was never going to date her. I would have changed that one. Even if my parents were proud to be Lipschitzes, or Embezzlers, I would have left the dock on that one.
We just played at a wedding and the brides last name was Lazorchick. . . I just wished her groom had the name “Frickin” so it could have been the “Frickin-Lazorchick” wedding. But, I’m sure it was pronounced “La-Zore-Chick” or something like that. . . Eileen Frickin-Lazorchick. . . that would be a cool name.
If my name was more than just odd, yes, I’d get it changed as soon as possible without a second thought.
Even relatively ordinary names can pose some difficulty. I once dated a woman with the last name Kirsch, who said that she was inclined to hyphenate when married. She was a bit troubled when I told her to avoid any man named Platt.
Nice to meet you, Mr. Incredible. 
It gets worse as time goes on. One generation hyphenates with the wrong man, they have daughters, and then you’re stuck with the Small-Kuntz sisters.
My aunt’s husband was named Belcher.
As you can tell, I’ve kept my unusual last name.
I don’t have a weird name, although when I was a kid comments along the line of “hey, are you related to that currently-famous athlete who spells his name differently and is a completely different ethnicity?” got old.
Lots of Weiners pronounce it why-ner, and they’re not being prudish. That’s closer to the original pronunciation (more like vye-ner). A different surname is “Wiener” which is wee-ner/vee-ner.
National Lampoon Presents True Facts: the Big Book compiles lots of these. IIRC one announced the marriage of a couple along the lines of Dick-Kuntz.
Aww. That puts her in company with Iris DeMent, and that’s pretty good company.
I don’t get it? The sound makes me think werewolf, not Dracula.
I used to know a lady who introduced herself as Margo K, and I thought it was Kaye, as in Danny. Everybody else thought so, too.
At her wedding, I met her parents: Mr. & Mrs. Klotz.
I believe she had the name-change paperwork in the mail before she left on her honeymoon.
I dated a gal with the last name Kuntz. It came from her ex. She hated the name enough she considered not marrying the guy years earlier. She said it was better than her maiden name, Dick.
My maternal grandmother’s maiden name was Koonce, IIRC. I might have the spelling wrong.
I acquired a very rare (but not embarrassing) last name by marriage. It has been my name for many years now, so I am keeping it. It is something of an icebreaker when I introduce myself, as it is a name that lends itself to several jokes, all of them mild. My birth name was not common, but inoffensive.
I saw a name the other day that seemed unfortunate: Raper. That would be a dealbreaker
It sounds to me like they were made for each other.
This sounds like a Judd Apatow movie waiting to happen.
We’ll have to assume both the count and the werewolf are to be found in the same outdoor setting at night; with mist on the ground, a bright moon above, and a dog or wolf howling in the distance. It’s not practical for basketball fans to play a specific Dracula theme song, like The Count’s organ music in Sesame Street, or the Moonlight Sonata.
Not weird but I know people with extremely common names like Jones and they get tired of being confused with others.
Some cousins had the traditional dutch name of “Ennema” back in the old country. They held onto it for a few decades in the US before changing it.
Good move on their part, IMHO.
