I come from a family of Ashkenazi on my father's side and from Sephardic origins from my mother’s family.
I once asked a learned man “where does it leave me?”.
The answer “absolutely nowhere!”
Thank G-d for the State of Israel, because it no longer matters!

P. S. Anyway I was named after my grandfather who passed away. However surely they are named ref: Dutch side, with the fathers name in the middle . Shall we say "ben", but it is not used
