This is like playing a crazy word game. I was awake at 5am thinking of combinations (I know I need a life...)

How about

AIM - Aimee/Amy Isabelle, Amelia Isabelle, Amirah Isabelle
SUM - Summer Ursula (might need to find some lovely African spiritual U name)

Then things just go down hill:

ELM - Elmo Liam, Elmer Lincoln....
URM - Urma Rose....

Off to get a life now
