Hey, I’m [name_u]Ashley[/name_u] - I’m 17 soon, and even though my parents never gave me a middle name at birth, I’d really love one. I’ve decided deed poll is probably the best way to go, and have shortlisted a few…

I’m about the same age as you, I just graduated high school this past [name_u]June[/name_u] and one thing I noticed looking at the massive list of names of all my classmates is how common some middles names are (think [name_u]Lynn[/name_u], [name_f]Marie[/name_f], [name_f]Rose[/name_f], [name_f]Grace[/name_f], [name_f]Leeann[/name_f], etc.) so having that in mind definitely influenced my suggestions! I don’t know how unusual you want it to be or if you want a middle that’s more common for people our age so I tried to give you a variety 
[name_u]Ashley[/name_u] [name_f]Megan[/name_f] H - Probably my least favorite but still a good choice
[name_u]Ashley[/name_u] [name_f]Clara[/name_f] H - It’s okay but I like it less than [name_f]Sofia[/name_f] and [name_f]Victoria[/name_f]
[name_u]Ashley[/name_u] Sofía H - I like it! The one thing is that having the accent might complicate some paperwork and stuff because people might forget about it or ignore it
[name_u]Ashley[/name_u] [name_f]Victoria[/name_f] H - Flows nicely, I like the variation in syllables

I think all your choices flow really well! I think [name_u]Ashley[/name_u] [name_f]Victoria[/name_f] is my favorite. I think [name_u]Ashley[/name_u] [name_f]Clarissa[/name_f], [name_u]Ashley[/name_u] [name_f]Gwendolyn[/name_f] and [name_u]Ashley[/name_u] [name_f]Genevieve[/name_f] would be beautiful.
I like [name_u]Ashley[/name_u] [name_f]Sofia[/name_f]! As an [name_u]Ashley[/name_u] myself, I’ve always been partial to [name_u]Ashley[/name_u] [name_f]Maria[/name_f] and [name_u]Ashley[/name_u] [name_f]Nadia[/name_f]. If I changed my middles, I’d be [name_u]Ashley[/name_u] [name_f]Eleanor[/name_f] [name_f]Grace[/name_f]. I think [name_u]Ashley[/name_u] [name_f]Hope[/name_f] and [name_u]Ashley[/name_u] [name_f]Lillian[/name_f] would be really nice, too. Or [name_u]Ashley[/name_u] [name_f]Aurora[/name_f]?
I think all 4 of your choices are lovely names and work well with [name_u]Ashley[/name_u]. My favourites are [name_f]Victoria[/name_f] then [name_f]Megan[/name_f].
