“As I understand, Muslim women have not custumarily changed their names when they marry; though some more modern women have done, especially some high-profile women.”
Rashida Tlaib’s maiden name was Harbi. She married someone named Fayez Tlaib (now divorced), that’s why her last name is Tlaib.
So why does her grandmother have the same last name?
I didn’t realized she had changed her name on marriage.
But don’t a lot of these people often marry cousins? That could make a name show up more than once in a line, depending on the level of consanguinity permitted. When it comes to cousins, even first cousins, there don’t seem to be restrictions among many of their sects.
Because first ol' Fayez married the grandmother. Having gone insane from that experience, he blindfolded himself and married her granddaughter. "All in the Family" must be their theme song.
