I know the Chasam Sofer wrote a teshuva about giving children more than one name, but it mustn’t have been all that bad as he gave his son 3 (Avrohom Shmuel Binyomin)…
Shmendrick – I have to wonder, when does tradition start? Is it the 18th Century (see thread on davening from phones…) or is it before then (as here)? Either tradition starts before the 18th Century, in which case 1 name only is traditional and learning from vilna Shas and wearing black and white is not, or it starts with the 18th Century in which case the reverse?
