What do you think of these twin girl names?

I personally think Set 3 is the best. Both names in 3 are pretty but provide some contrast, so each girl will know she is her own individual person. The first two, with the Isabelle and Abigail ending with 'L' and the Lilly beginning with 'L' it just doesn't roll of the tongue as well. And Emma Lilly kind of blends together into Emmalilly when you say it out loud. Set three is the best one! Good luck with your adoption. Thank you for doing something so nice for these twins. Best wishes! :)
