When I first started this webpage, we thought that Aron had a few sibings. However, as of my research as of 2022, we can only positively name one of Aron’s siblings: Judel Reuven. Why?
In the past we thought my Aron was the son of Ber, son of Mordekhl. Mordekhl does have a son named Ber. However, if you go back to the Aron page, you will see that we proved that “my” Aron was the son of Ber who was the son of Isaac.
