I'm looking into the origin of my friend's name, Coryan. He was named after a deceased family friend of Romani descent, so I'm assuming the name has Slavic or Middle Eastern roots. It may have been a nickname.
I've found the names Goryan and Goryana, which may be cognates, listed for June 22 on a Bulgarian name day calendar, but I can't find their definition/origin online.
To summarise: Coryan, male, Romani origin, possibly nickname
