I know of a few women who are named after their mothers. My mum disliked her own name intensely and was also annoyed that her mother gave her two middle names for aunts that her mother didn’t get on with. She refused to use any of those names for me so I have a completely different selection of names to like/dislike/refuse to use.
In my partner’s family, there are several males with the exact same first name/surname. He has the same first name/surname as his father (although he’s not the eldest son in the family). Both his uncle and cousin also have the same first name/surname, although in their case the first name is the same as my partner’s older brother. Also, his mother and sister-in-law share a common first name. No wonder I need a diagram to work it all out.
