Even in Dracula Untold, you have him walking around centuries later, and he notices a girl that resembles his anciently-dead wife, that fell from the tower.
He asks her her name, and she says "Mina".
So you have:
Matthias with Elisabetha. A tragic death, which starts his quest to find a way to defy Death and Mortality, seeking out Leon and his ambition with the alchemy dabblings of Walter Bernhardt.
Matthias (as Vlad Dracula III) with an unknown woman, his first wife as Dracula, who threw herself from the Tower ("I would rather have her body be eaten by the fish of the Argeş than be captured by the Turks." Causes him to defy God Himself.
Vlad Dracula III with Ilona Szilágyi a.k.a Jusztina Szilágyi, a fraternal cousin of King Matthias Corvinus of Hungary. "Dracula" 's 2nd wife. If we were trying it all into Castlevania canon, this wife may be fictitious, as she is 'cousin' to the Matthias Corvinus that Matthias Cronqvist seems to be based on.
Vlad Dracula III with Lisa, with whom he has a child named Adrian (somehow), and she is killed by mankind, starting his war with humanity. Lisa is a woman he seems to have fallen in love with, but I am not sure whether they ever exchanged the vows of Marriage. I think he may have just been a visitor to her and her knowledge of medicine and healing, or perhaps magic, is what drew him to her, but love kept him from turning her. Her genuine goodness sparks his hatred for humanity. He has already found a way to defy Death, and was already angry at God. This was the last straw, which drew him to hate Mankind as well. This is when he begins to really dwell in sorcery and witchcraft and becomes a warlock.
Vlad Dracula III (as Vlad Tepes) with Mina Harker. After his many reincarnations, Dracula finds Mina Harker as per the Stoker novel, whom he seems to think is the reincarnation of his original wife (whether that is Elisabetha as Matthias, or his unnamed wife as Dracula III who falls from the tower, we do not know for sure).
Soma Cruz with Mina Hakuba. Even the "Hakuba" surname reminds you of "Harker" a little.
