A name starting with an S ending in an s with a two part last name the first part St. is is too much? Think [name_m]Seamus[/name_m] St. Two syllable
Nope, I think that alliteration is adorable! I have a first and last name that sound very alike and am always getting complements 
I don’t think it’s too much at all. Especially since [name_m]Seamus[/name_m] starts with a “sh” sound. Sounds like a lovely name, in fact!
It absolutely works here.
[name_m]Seamus[/name_m] was my example but it’s not too much? I’m never sure what the rules are with that. Obviously she may get married and not have the last name anymore too.
