The Prof:
You said:
The Uheler Rov in Hungary, Binyan Dovid, once said in a speech. The Hungarian Jews before WW2 always gave secular names. This upset him. He said, Yakov Oveenu gave us a brocho: Hamaloch hagoel osi, yevoreich es haneorim, v’yikorei bohem shmi v’sheim avosai. The angel who always protected me and redeemed me, should bless the Jewish children. When you send someone a letter, you need the correct name and address. Yakov said, I’m sending you an angel to protect you. But he’ll only know who you are if you call him by my name and the names of my father and grandfather, Yiddishe names, not Robert or Tibor.
First, that’s your experience, not mine. I know a Chinese attorney whose name is Na. That’s quite easy to pronounce but she goes by Linda. Why? To fit it and not get distracted with a conversation about her name.
(Repeat the following in an Indian accent: “Microsoft technical support. How may I help you? My name is Steve.”)
Also, regarding the quote you attribute to “the Uheler Rav,” I assume you are referring to the rav of the place in Hungary formally called Satoraljaujhely. My mother’s family came from there. Needless to say, they all had both Hebrew and Hungarian names which might give you an indication how this IDEA (not Halacha at all) was received.
