What's in a name? Alot according to Chazal.
The Bostoner Rebbe shlit"a of RBSA was speaking during kiddush about names. The Rebbe said that we give Jewish names to create a Jewish identity for our children. Even names that have non-Jewish origins once they were adopted by the Jewish people and became "Jewish" names serve the same purpose.
This is why the Midrash teaches us that the Jews while in exile in Egypt known as Galus Mitzrayim where redeemed in the merit of the fact that they did not change their names, the style of clothing and their language.
These 3 factors are of prime importance because they create an "identity" in this case a Jewish one. The Egyptian exile is the only exile we faced before Matan Torah, before we recieved the Torah at Mt Sinai. Throughout each other exile we survived with our holy Torah protecting and guiding us. Egypt was different we had no yet recieved the Torah how did we survive that exile?
Jewish identity; created by a distinction of dressing differently, speaking differently and being called by different names.
Whats in a name? identity.
