I hear sometimes people being called up to the Torah as "Ploni Ben Avraham Avinu" I assume that these are people who - by their own choice - wish to advertise that they are converts. (I also assume, that most geirim are more circumspect, and prefer to be called up as "Ben Avraham")
Does anyone know more on this?
When being called to the Torah, is a convert required to give his name as “Ben Avraham Avinu”?
