that is not really new anyway, it was used on feudal eras on east, when the female family was more powerfull then the male one, and the male one family had other heirs, used mostly when the the family only had girls and not boys and the father was not willing to adopt a boy to heir his name.
but by nowadays? why I would do? I have a royalty name (6 names long lol) why I would make it shorter and even change? be happy I let you tag long enough to let you marry me.
also like I said about this last time, he is a artisty and want to use his wife name to boost his lame work, or is a idiot whatever is the case that shouldn't change much
