They're both nice names, but I don't care for the MNs much. Even though my mom's MN is
Jo, I just don't think it goes well with
Leah. I think
Leah Josephine and
Ava Lynette would have work nicely, and the still would have honored their parents. But all together, I think the names work well as a twin set. Congrats to you and your family!
