I have neices, and they were huge
Hannah Montana fans, so
Rico reminds me of that.
But for a horse? I kind of like them both. So...maybe I'll go with meanings:
Dallas: meadow dwelling
Rico following the Spanish side: Brave power
Rico following the Italian side (turns into
Henry): Home ruler
I used this site, so if this site is correct, then I really like "Brave power" for the horse who is going to be strong. So
Rico
Although, if you want a more laidback name, meadow dwelling also works...
Hope I helped a little bit...
