Q. I'm dating someone whose mother had my Hebrew name as a nickname. Is this an issue? Can he call me a Hebrew nickname instead?
A. On question 3493 we were asked:
“Our daughter, who is having a difficult time finding the proper shiduch, was B’H able to connect recently with a promising candidate. But now a new issue appeared. The name of the mother of the proposed chosson, is the same as hers. Can she now add a name to hers, so the names will not be the same?
How about if the mother of the proposed chosson is the wife of a Rabbi, and she is usually called Rebetzin by all, and not by her first name?”
To what we answered: “The tradition of both the groom and the bride not sharing the names of the counterpart parents, is based on the Tzava’ah or last will and testament of Rav Yehuda HaChasid, written in the beginning of Sefer Chassidim.
On question 175 in regard to shunning a marriage to a woman whose father's name is the same as his we wrote that
“this is to be found in the Will (letter 23), where he adds; And if he did marry her, he should change name, maybe there is hope. Some retrace the above to the Arizal (Mizmor Leasaf p.110).
A number of reasons are given: Firstly, Ein Horah (evil eye, Chidah Bris Olam 447 Heishiv Moishe 69, Chazon Ish, Maase Ish 215 ). Some maintain that it will cause an infringement in the respect due to the father, as his daughter will call her husband by his name in front of him. (Yad Shoul Y.D. 240 Mevakshei Torah 24 p.155).
Horav Shlomo Miller's Shlita opinion is that there is no concern if the names are not exactly the same.”
Some Poskim maintain that the Tzava’ah applies only to his family and descendants (Noda Beyehuda E.H. 2: 79). However, others maintain that it refers to all. Therefore, usually people are indeed careful.
Divrei Chaim (E.H. 1: 8) mentions that in his circles, they specially avoid marriage when the name of the bride is the same as her future mother in law. A similar opinion is to be found in Tzemach Tzedek (Y.D. 116) quoting the Baal Hatanya. However, he permits changing the name in a minor way, as do others.
Indeed there are Poskim that also maintain that if the mother in law id usually named by a given title, such as Rebetzin, there is no concern. (Tirosh Veitzhor 214).
Horav Shlomo Miller’s Shlit’a opinion is that for those who maintain that tradition, indeed they can be lenient.”
In your case the Rov Shlit’a answered similarly, and he added ‘Man Delo Kopid lo Kopdinon Lei” meaning if one is not bothered by the above since that is not a family tradition, we can also accept it.
