One of the most popular name for baby boys post churban Beis Sheni was ALEXANDER, in honor of Alexander the Great. It is not a new innovation to name after leaders of countries. As a matter of fact, chazal requested all baby boys to be named Alexander as a mode of hakaros hatov.
Names are cultural and personal. In the city of Efrat, you will not find a child named Yoeli, while Williamsburg does not have boys named Yair or Evyatar (both Bibilical names). Mighty difficult to find a Yiddisha name among Sefardic Jews, or an Israeli name among Chassidim. IOW, so what?
Lashon Hakodesh has changed over the years, there is lashon hatorah, lashon tanach, lashon chachomim, lashon hamikreh each initiating new verbs, words and expressions. Be a yid, act like a yid, light up the world in holiness and be proud of whatever is your given name. Reb Moshe Feinstein zt”l ruled against parents who named a child a name that would cause them ‘shame’ in the future, a child must and should love his name.
