Yiddish Names/English Names/Hebrew Names
If some people have a Yiddish rather than a Hebrew name that is used for ritual purposes (e.g. getting an aliya, praying for the sick), can one have an English name for ritual use? What makes it so a Yiddish name can be used, but no one uses English names ritually? And what if someone only has an English name, but none in Hebrew or Yiddish? Can that person (or their son) receive an aliya under an English name?
