If they dropped into my lap right this second then
Joanna (
Asia),
Ada, and
Emma are most likely. Although, I already have a close relative nicknamed
Emi, so maybe
Lidia or
Jagoda instead of
Emma. I suppose if they I was having triplets, I would conduct whole surveys with friends and family for best ideas, I wouldn't just stop at whatever popped into my mind.
