Hebrew speaker here. I’m sorry to rain on your parade, but Harry is NOT a Hebrew name, and the closest Hebrew word is “haray,” which means “with this.” (It’s part of the Hebrew wedding vow, “with this ring I thee wed.”
If you search for the Hebrew meeting of Harry as a name, you get Khatriel, which means “crown of God.” It doesn’t sound like Harry, and it’s not remotely close to Harry.
I won't argue, because I don't know Hebrew, as I said when I first posted it, I had looked up what my dog, Buttercup's name meant, and for laughs and giggles also my dog, Harry's name. I was surprised when it said the name was of Hebrew origin, but was more interested in what it said the name meant, because that fit who or what Harry is. I just Googled it a minute ago after reading your post and got the below.. If anything it is an illustration on how while a great research tool, what you learn on the internet does have to be taken with a grain of salt..
Home ruler
Meaning: The meaning of the name Harry is: Home ruler. It is of Hebrew origin, and the meaning of Katriel is "my crown is God".
Google can screw up.. I also got;
Harry means “home ruler” (from Germanic “hagan” = enclosure or “heim” = home + “rihhi” = powerful/rich/mighty/ruler) and descending from Harold, it means “leader of the army” (from Old English “here” = army + “weald” = power/ruler/leader or “wealdan” = to rule).
Here is the more likely cause for the confusion, according to the "Jewish Lexicon";
Etymology
Likely from "Harry," an English given name common among English-speaking Jews, used pejoratively to imply that the subject is less devout because he goes by an English name instead of a Hebrew or Yiddish one.
