Would this be tacky?

I think matching names are fine if they don't make you bit your tongue...Emilia, Eliza and Ellis could be nicknamed Milli, Liz and Eli and you have no problems. It would only be on paper that there's alliteration. I don't know why people make a big deal out of it...the kids are going to be individuals even if you named them all Bob or they were born conjoined...a name can't change that.
