names for triplets

my husband and i just found out we’ll be welcoming triplet girls via adoption in 2 weeks. we are so stunned and woefully unprepared to name these babies. we’re looking for names that go with the name Sophie, our first born. we would love to use the name Nell since it’s a family name and love other names like Kit, Violet, Wren… but nothing seems to be flowing altogether- help! we also do want middle names, currently we have Sophie Rose. 6 names in 2 weeks is a problem we never thought we’d have.
