I have both [name_f]Alessia[/name_f] and Olessia on my list, and I want to get rid of one
I know [name_f]Alessia[/name_f] is the original name, but good nicknames are really important to me and I love [name_u]Ollie[/name_u] (it would also be an honor name to someone really special name to me named [name_f]Olivia[/name_f] nn [name_u]Ollie[/name_u]) and I hate [name_u]Allie[/name_u]. What are your thoughts? Thanks in advance!! 
[name_f]Alessia[/name_f] looks prettier.
I would stick with [name_f]Alessia[/name_f].
I prefer the sound of [name_f]Alessia[/name_f], but if you prefer the nickname [name_u]Ollie[/name_u] then perhaps Olessia is a more logical choice.
Olessia reminds me of [name_f]Olesya[/name_f], which is a real Russian/Ukrainian name.
