Blaise

Also the name of a saint: https://en.wikipedia.org/wiki/Saint_Blaise

Blaise was also fabled to have chronicled the Holy Grail tale, where King Arthur of Camelot went forth with the knights of the round table in search of one of the most famous relics. In the overall story, Blaise was a priest who was present at Merlin’s birth and guided him through his growth in order to control his good over evil. Blaise saw the potential danger but also good in Merlin as the tale tells that Merlin was born from the conjunction of holiness (his mother was a nun) and evil (his father was a demon). Blaise would council Merlin throughout his life, suggesting to Merlin to tell Arthur of the quest of the Holy Grail and of its importance.

Blaise Zabini is a character in the Harry Potter series.

There has been a major discussion among the "Harry Potter" book fans as to the gender of Blaise Zabini, until it was confirmed by the authoress that Blaise is a he. I personally cannot see anything feminine to this name, but apparently there were some who did.
