My name is Andriana, and it is a malgache name, from Madagascar. It means princess and/or prince, queen and/or king and is more usually used as a family name except in my case. In my case it means princess.
This is a Greek name found most often in the city of Patras and the surrounding areas. It's a feminine form of Andrew, so I guess it's related to Andrea in that way, but it's not related to Adriana and is not a composite of the two. [noted -ed]
