First of all, I’m pronouncing Lange like “lane” but with a “j” sound, so more like “laynj.” Not sure if that’s right.
I actually feel like [name_f]Jennifer[/name_f] sounds the best. Most of the other options are heavy with the “ay” or “ah” sound, just like Lange is. The ones that aren’t ([name_f]Nicole[/name_f], for example) are heavy on the “l” which also runs into Lange. [name_m]Even[/name_m] though I don’t like [name_f]Jennifer[/name_f] that much as a name, and any one of these are fine if you prefer them (except maybe [name_f]Nicole[/name_f] and [name_f]Dahlia[/name_f]), [name_f]Jennifer[/name_f] is phonetically the best.
Voted for [name_f]Corinna[/name_f], but I also like [name_f]Johanna[/name_f] and [name_f]Helena[/name_f] with Lange. [name_f]Danica[/name_f] and [name_f]Jennifer[/name_f] work well too, but I don’t like the names as much.
[name_f]Hailey[/name_f], [name_f]Nicole[/name_f] and [name_f]Caroline[/name_f] were the hardest for me to say with Lange.
I voted for [name_f]Corinna[/name_f]-- recognizable but a little different. I think all the names without an L work better with Lange (I’m also pronouncing it as lane-j).
I voted for [name_f]Dahlia[/name_f] because they all sound ok but [name_f]Dahlia[/name_f] is the prettiest and I’d rather have a pretty first name than one that flows;)
The only one that is a bit of a tongue twister is [name_f]Caroline[/name_f] Lange so I think you should just pick your favourite from the others. You have a nice list.
