Suggest a family name and two boys for me

Hello Rabbi, my name is Jona, and I converted to Judaism years ago, but I haven't been officially accepted yet. However, we pray together in my town once a month because our numbers are small here. My question is: I would like a family name of Jewish origin that is short enough to register my children with, as I have brought my family into my faith and they wish to share my belief in the God of Israel.
