Surnames or family names are a relatively (last few huindred years) invention. In fact, in some countries (like Iceland) family names are still not used. Instead the terms Fred, son of Bill, or Mary, daughter of Joan are used - where we get names like Donaldson, Robertson, Jackson etc today. In some countries like Scotland the term 'Mac' as in Macdonald means 'son of'. In Wales, the terp 'ap' means the same as in ap Evan (shortened to Bevan) or ap Rhys (shortened to Price). In Ireland the term 'O' means the same thing as in Keiren O'Connor. Also in Moses' day there were no surnames as we know them, so neither Aaron nor Moses had a surname. The Jewish form of 'mac', 'ap' or 'O'' is the term Bar. So James and John who were sons of Zebedee could be called John Bar Zebedee and James Bar Zebedee. The Bible states that Imram was the father or Moses, although Bible scholars doubt this. So if this was true, Moses would become Moses Bar Imram, and Aaron, Aaron Bar Imram.
As of 2020, there were estimated to be over 750,000 individuals named Aaron in the world.
