Konami might have also got Grant's last name from the real life village with different spelling, just like how they got the name Elisabeth Bartley from a real historical figure Elisabeth Bathory or Mathias Cronqvist from the name of King of Hungary Matthias Corvinus.
I hope to not come off as an asshole if I quote myself:
Kolde reiterates Ellis' justification, that there is a town called Danesti and Grant may have been named after it. They keep coming with convoluted rationalizations to imply Grant's existence is meaningless, and that makes me think they have something against the character. It's impossible at this point that they don't know that House Danesti was a political enemy of House Draculesti, which Vlad belonged to, giving the name a much more important historical role than a "town name". So I'm forced to conclude they just think the character is crap and want to downplay him.
Could Konami have based themselves on the town name? Yeah. Is it likely given that Grant is portrayed as actual enemy of Dracula in the game, and there was an actual "House Danesti political enemy of Vlad III" at the time Vlad existed? On my opinion, no.
Still- Even if Konami DID base Grant's name on the town, "House Danesti opponent of Vlad III" seems way more important than "romanian town name". This is a wikipedia search away, which is why I think these guys know this, but insist on the "town name" thing to downplay the actual historical importance of the Danesti. Funny when you consider they wanted it to be so "accurate" to the time period. But of course, this is just one of many details that, to me, suggest they just want to bury Grant.
Even burying the character is fine by me, what is not is the constant provocation. One thing is "we are not having Grant, sorry fans!", another is "we are not having Grant AND we are also making fun of those who want him, they're so silly right?!" also "Oh and this character is obviously portrayed to be a Grant stand-in? Not Grant lmao".
