Ashkenazi and Sephardi
The Naming of Ashkenazi and Sephardi Babies
The minhag (custom ) I chose is the naming of babies. Sephardi and Ashkenazi Jews both have different customs on how they choose to name their new babies. For example the Ashkenazi Jews name their new babies after close relatives that have died and are no longer alive when the baby is born. On the other hand Sephardi Jews name their new born children after their close relatives that are still alive when the new baby is born. The Ashkenazi Jews name their babies after close relatives that have passed away because they had a strong tradition that the baby had to be named after a deceased relative. This is not a Jewish law but a very important tradition to the Ashkenazi Jews. Why do Sephardi Jews name their new babies after a close alive relative? Many Sephardic grandparents look forward to feeling honoured with grandchildren who share their own names while they are still alive to see it. Overall, among both Sephardic and Ashkenazic Jews, there is a custom of naming a child after someone, usually a family member.
This Minhag (custom) helps the Jewish community survive in the diaspora because it helps Jews identify as Jews, by having Jewish names that are different to the name in the surrounding community.
This minhag does not help you to adapt to your new environment because your name is so different to the new environment, that you stand out. This means that your name doesn't blend in with you new environment.
