I have never met a woman named after her own mother

I agree with all the sentiments in this thread about giving a kid their own identity and would never name my kid with my name even tho it could go to either sex depending on spelling. However the exception I would have to this sentiment is when someone names their kid after a deceased loved one. Usually would be the soon to be born kid's grandparent or great grandparents. So like if someone is best friends with their dad and their dad passes before their grandchild is born the person will name their kid after their late father. I dont think I know any specific person who did this with the first name, but I have seen it a ton with a person's middle name. I think its sweet and is a nice story to tell a child.

This got me thinking about how there is no female equivalent of junior or senior
- I always assumed it would just be the same, but now that you mention it I've never met a female junior
  
  That's what I was thinking

My mother, grandmother and great grandmother all have same name, but used different short forms to differentiate.

I know someone who has the same name as her mother, and her grandmother. They all lived in the same household. Imagine, you call her name and all three of them listen.
I never understood this practice in general, regardless of gender. There are so many possibilities, sure it takes some creativity, but it's not that hard, come on.
- Never have I ever met a family with a shared name.

I believe every woman is named after their mother. Usually by about 20 years or so.

My wife's g-grandmother was Mary. Her daughters were Mary Margaret, Mary Agnes, Mary Elizabeth, and Mary Alice. Newfies.
- Are they Irish?
  
  Newfies are Irish in the same way that Quebecois are French

Good. Let kids have their own identity. I've always cringed at the Ebeneezer Gortlegump IV's of the world.
What I have seen is it is much more common to have the firstborn daughter have a middle name of an ancestor, often grandmother.
- Can confirm myself, my mother, and my maternal grandmother all have the same middle name. Call it a southern thing I suppose. I killed the tradition by being childess and my younger sister refused to pass it to my niece.

Yes you have. They're just better about it.
I've met so many mother daughters, including my own mother and grandmother, who just alter their own name a little bit instead of going for a "Junior" type deal.
For instance, my Nana's name is Elizabeth but goes by beth. My mom is Eliza Beth-Ann but goes by Eliza or Liz.
(Also yes I'm from the south)

The weirdest combination I've ever met was a set of female twins. One was named after their mother. The other had a different first name. Must have been really odd when growing up.
- Should have given them both the same first name, and dressed them the same as kids. Taught them to speak together in the same voice. Then used them to committ tax fraud.

Yet I'm sure they exist.
From some random article:
Naming a daughter after a mother isn’t a modern phenomenon; in some cultures, the tradition of matrilineal naming goes back centuries. In Ireland, and several other European countries, it was commonplace to name the first daughter after the maternal grandmother, the second daughter after the paternal grandmother, and the third daughter after the mother.
The practice is also prevalent in several Spanish-speaking countries, where it’s common to carry on both parents’ last names as well.
And then there's Iceland.

Me wife is a woman with her mother's first name as her middle name.
And of course my father in law is a fourth generation jr

Do middle names count? My grandmother's first name became my mother's middle name. Then my sister and her daughter also got that middle name.
- My sister was given my Grandmother's middle name as her first.
  But I don't think those count. Many men are "Jr." OP's right, very few women are "Mom Jr." What would the suffix be? Junior? Is junior non-gendered? I think of it as a masculine suffix.
  Good shower thought.

I know one, but it’s a little complicated. The woman is named Ann, and this is because when she was adopted at birth, the adoptive parents named her after the biological mother, also Ann. So yes and no.

My mother was named after her mother. It's the only instance I can think of though.

My mother's name is María, so are three of my sisters. Their middle names are different though.

My mother was named after her mother, although she used her middle name. My sister was named after her. We're white midwesterners in the US.
