[name_f]Margot[/name_f] [name_f]Shannon[/name_f] sounds PERFECT!
[name_f]Shea[/name_f], [name_f]Nora[/name_f], and [name_f]Margot[/name_f] are great choices. I don’t think [name_f]Shea[/name_f] [name_f]Shannon[/name_f] is a problem.
The one that is hardest to say is “Nee-sha” [name_f]Shannon[/name_f]. The sha-sha runs together a lot there.
