I actually don't either. There are some I hate and others just just aren't my style. Why do celebrities feel the name to pick such weird names though? Is it supposed to be the trendy thing to do?
Sparrow is a guilty pleasure name but would go with Wren.
Believe it or not, Sparrow is a family name on my dad's side! If we have a girl we hope to use it as a mn, if it goes OK with whatever we decide on as a fn.
