Since triplets already share the same DNA (although somewhat rearranged in each), perhaps they should also share the same letters in their names (also somewhat rearranged)?
Of all the names you gave, here are the pairs (for first & middle names) that produced the most likely sounding anagrammed names to go with them.

(
Daisy ,
Lydia , and
Sadie were my favorite choices for your triplet girls. Plus, they go well with
Ethan -- they are all 5-letter names.)
