I've been looking up this name on a lot of sites, mainly because I've used the name for a female character. According to this site, it could be an anglicized name of
Urien :

It could also be a French (male) variation of the name
Oriana :

But then this site claims it's a unisex name meaning either gold, sunrise, or dawn for the female version, which is supposed to come from Old French, or limit, boundary, or urine for the male version of the name, coming from Old Greek.

I don't know how reliable any of these sites or their information are. But it's interesting because I came across this site that lists the survivors of the Titanic, and this name belongs to a female survivor named Orian Davidson, and she's supposed to have been born in 1884. I hope this helps you a little, even though I've given you nothing concrete.
