My ex-husband had only his Hebrew name and it is Avrom. I constantly received phone calls for Abner and Ivan and Avery. Once after 3 of these calls in a short period of time, I told my father in law that the fact that he had not given his son a secular name, as well, had done him a great diservice. In the age that he grew up, I truly believe this – he was an underachiever in both school and the working world. I can’t blame all of this on his name, but certainly some of it.
FYI – I used to have a Chinese friend who had an “English” name. She told me that the educated Chinese and those in the business world (in North America) add an English name to facilitate business dealings. The less educated – she used the example of Chinese restaurant workers – usually do not adopt another name.
