The name Alianna is a girl's name . Alianna and is often added to user-created lists like Adorable A's and discussed in our forums with posts like "Change One Letter".
From the experts:
Alianna barely wedged its way into US Top 1000 in 2015, and almost fell off with a Number 998 finish in 2016. The second n doesn't add much, so Aliana or even Eliana might be better options.
