Not in the English version no. But apparently Merengue's German name is Maria according the Animal Crossing Wiki so there's that. One of the reasons why I like her and want her in my New Leaf town that I've just started up unfortunately no room for her in my NH island. I hope in the future there's a character named Maria in the English version.
On another note, my mom shares a name with Rhonda the rhino. Which I was surprised with because I've never met another Rhonda besides my mom.
I share my name with Lucy the pig! Shes cute but i’m not as big a fan of the pigs ( but she is super cute
~a family members name is cally and she NEVER finds her name anywhere spelt how she has it! she was tempted to get new horizons when i showed her cally the squirrel xD
My names Lucy, I share the name with one of the pig characters. I like the pig characters but I'm not so keen on this one, although I was born in the year of the pig so it's a funny coincidence
I don't because my real name is very uncommon, but Marina's is close and I do love her! I have her on my island in NH and she's constantly singing and is so cute.
