I laughed so hard when I read that. It definitely gives me an idea that might get me killed... Anyway, I've never been a fan of naming kids after anyone, even in middle name. In my family, I have my brother and like three cousins (I lost count) named Daniel, Two cousins named Betsy, and like 6 aunts named Maria. Keep in mind all my cousins are first cousins and my aunts are all eachother's sisters. My mother (their sister) is also named Maria, by the way @_@. The whole situation is just crazy and confusing. This is partially why I'm only breeding once and naming my kid something ridiculous like Ganondorf, they won't copy @_@.
Other than converting to a religion that doesn't allow you to name a kid after someone who is still living, I got no advice XP. Maybe tell her that you'd rather name your kids a name you can both choose? I'm just gonna shut up because I got nothing good to say XP.
