Middle Name Needed for girl Austen

Right now our top contender for our baby is [name_u]Austen[/name_u], yes for [name_f]Jane[/name_f] [name_u]Austen[/name_u]. Our other daughter is named after an author and her name is also considered unisex /boy. Our top middle name choice is [name_f]Rose[/name_f] right now. I want something more feminine for the middle name of [name_u]Austen[/name_u]. Our last name starts with a P and contains 3 syllables. Thanks for any suggestions for a middle name
