What do you think of [name]Seager[/name] for my son? My daughter’s name is Maven. We’re victims of hurricane [name]Sandy[/name] and [name]Seager[/name] means “sea fighter” - if you dislike please tell me why and make other suggestions for Maven [name]Peri[/name]'s brother.
I personally like it I think it goes well with Maven and I think it’s nice to have a story to go with a name so the meaning of this name goes great with story that your trying to portray about hurricane sandy. Goodluck to you!
I generally like the sound of it and love the backstory so I say go for it. I will add that my first image was of the singer [name]Bob[/name] [name]Seager[/name] but I don’t think that’s a reason not to use it.
I’ve made the musical connection too. [name]Bob[/name] [name]Seger[/name] and [name]Peter[/name] [name]Seeger[/name] ([name]Peter[/name], [name]Paul[/name] and [name]Mary[/name])- I like them both so those are ok associations 
I like [name]Seager[/name]. It’s a nice name that fits well with your little girl’s name.
