The name 'Aaron' means 'Strong and powerful'. Its origins are in Hebrew.
It is believed names were first used to describe a person's actions or professions. Think about your surname, does it sound like it could mean more? Perhaps your surname is Singer and an ancestor of yours was an entertainer? Other names have gradually become more removed from their first iterations, whichever language they may have been in.
In some cases, words are still used as names. 'Hope' is quite popular in America, and its Spanish counterpart, 'Esperanza' is also quite popular in Spanish speaking countries. These names bear their literal meanings.
There is a theory that children in ancient times didn't begin to be called by names until they were around five years old (it is believed this is also the age many children weaned at), as when they reached such an age, they would have a more obvious temperament and be easier to give a name to that was more like a description. Examples of this are heavily present in the Bible, Enoch (meaning 'dedicated') walking with God, Mahlon (meaning sick) dying of a disease etc.
These theories can help you to get an idea of the way your ancestors lived their lives purely through understanding what their names meant, and in many cases people grow to be true to their names, whether consciously or not. It's a nice thought!
