Middle name names

What are your favourite names that you would probably only use as a middle name? Whether it be because they’re too out there or too popular or your partner has vetoed them as a fn. What are some names you love but only consider middle name material? At the moment all I can think of is [name]Willow[/name] (partner won’t allow it as a fn) and [name]Primrose[/name] (don’t have the guts to use it up front). I’ll post more as I think if them.
