No problem! I naturally pronounce it [name]Vivi[/name]-ahn-uh. The [name]Vivi[/name]-ann-uh sounds very nasally to me, and I tend not to like those wide vowel sounds. I do prefer the two “n” spelling, as I see you mentioned you do as well.
I love love love [name]Canyon[/name]. I think it’s great with [name]Cruz[/name]. [name]Canyon[/name] [name]Wilder[/name] is very cool and reminds me of a cowboy! I’m not as fond of [name]Texas[/name], but I don’t generally like state names. I do think [name]Phoenix[/name] goes along with the kind of names you like, [name]Phoenix[/name] [name]Jett[/name] is beyond cool. Some other names that come to mind: [name]Ace[/name], [name]Noble[/name], [name]Stone[/name], [name]Storm[/name], [name]Blaise[/name]/[name]Blaze[/name], [name]Dash[/name], [name]Nash[/name], [name]Forrest[/name], [name]Beau[/name], [name]Fox[/name], [name]Birch[/name], [name]Colton[/name]/[name]Colt[/name], [name]Sawyer[/name], [name]Flint[/name] and Strider. Also [name]Lex[/name]/[name]Rex[/name]/[name]Dex[/name]/[name]Dax[/name] all remind me of [name]Tex[/name]. And since you like place names, I can think of [name]Denver[/name], [name]Dallas[/name], [name]Cairo[/name], [name]Everest[/name], [name]Rio[/name], [name]Raleigh[/name], and my personal favorite, [name]Memphis[/name].
[name]Hope[/name] that helps!
