People can name their child whatever they feel is meaningful to them. If Eliana is a name parents love, there’s nothing wrong with that. Popular names come and go in every generation.
We already have countless Davids, Deborahs, Ades, Musa, Olus, Chichis, and plenty of Chi-something names. Every generation has its favorite names. If today’s parents love Eliana or Jaden, let them enjoy it. At the end of the day, it’s their child and their choice.
