Aryana was a country between 7000 B.C - 1700 B.C, in central Asia which included entire Afghanistan, eastern Iran, southern Tajikistan and northern India.
I wouldn't name a child this. For one, it has the word "aryan" within it, and that immediately makes me think of neo-nazis and other "White Race" groups. While I do like the modernizing of traditional names by changing a letter to "y" (Erin -Eryn, Megan -Megyn, April -Apryl, Lindsay -Lyndsay), I don't think it works for this name.
Am in total agreement with Irish Pearl on this one. If Hitler had a daughter, he may have named her this. The 'Ariane' names are very pretty but this one was crafted by someone with a pretty bad knowledge of twentieth-century history.
Sorry, the unfortunate spelling makes it look like something a white supremacist would name their child. I actually remember reading an article about a neo-nazi couple who had a baby Aryana. Aryana gives me the shudders.
