Charlotte M. Yonge,
History of Christian names
(1884)
“ A yearly feast was held at Sparta in honour of Hyacinthus, and his name was perpetuated till Christian times, when a martyr bore it at Rome, and thus brought it into favour in Italy as Giacinto; also a Polish Dominican Jacinthus in the thirteenth century, is commemorated as the Apostle of the North, because he preached Christianity in great part of Russia and Tartary; but curiously enough it is in Ireland alone that Hyacinth has ever flourished as a man’s name, probably as a supposed equivalent to some native Erse name. ”
