Angel, or Angelus, was sired by Darla (maybe Darlav was a typo?).
and it didn't work out between Angel and Buffy because they found true love in each other. unfortunately, Angel's gypsy curse reverses and he loses his soul when he finds perfect happiness and ceases to suffer for all the terrible things he did when he was the soulless vampire Angelus. this meant that they couldn't be lovers, only friends which is why they went their seperate ways and fans got two shows for the price of one.
the couple proved that the age difference thing didn't really matter at all.
