picking a baby name ....help

so my husband are are currently expecting baby #1 YAAAY ☺..... when it comes to baby names he's got boy names picked out and is pretty dead set on them I doubt I would get any opinion on a boy name. when it comes to girls names he wants the name mikayla marie. mikayla is his "adopted" sister who is still alive and we see her all the time. marie bc thats my middle name. I like the name but dont want to use it because we see mikayla all the time...is it just me or does anyone else think it would be wierd to use that name? how do we agree on a name???
