Last name origin & meaning:
Spanish and Portuguese: from the personal name Jacinto,
(Latin Hyacinthus, Greek Hyakinthos). This was the name
of a 3rd-century saint who was martyred together with his brother
Protus. He enjoyed a certain cult in Portugal. His name, which is
almost certainly of pre-Greek origin, in classical times denoted a
flower (not the modern hyacinth, but perhaps the martagon lily), and
it was borne by a mythological character from whose blood the flower
was supposed to have sprung up.
