Middle name frustration

Jewel

So my fiance and I have been trying to decide on what to make our little girls middle name. we are thinking Celine but his family is pushing for us to name her after his grandmother who passed away (Queen) we think it's a little too much but they are being very persistent about it since they wanted us to name our first little girl Queen. How do I tell them we don't want to name her Queen. BTW her name will be Madison Celine Smith
