Mine’s also Dawn. USA.
This, exactly.
Mine is Marie. My mother’s name is Mary, my grandmothers were Mary and Mae. Mae was my mom’s mom. So Marie was supposed to be an homage to all of them. And yes, we were Catholic.
My middle name is Seymour, I’m female, 49, born in the US.
Middle name: Eve (born in USA). It was my Russian grandmother’s name.
When I made my confirmation, I was told to pick a saint’s name from a list. All the Theresas picked “Marie” or “Ann”, and all the Maries and Anns picked “Theresa”. Being one of a handful of non-Italians, I picked “Monica” because it was different. I was weary of hearing the names ‘Theresa, Marie, Ann, Ann Marie, Theresa Marie, Mary Theresa, Theresa Ann’ all the time…I don’t hardly know how they told each other apart.

Mary/Marie is an incredibly common middle name in cultures with a high incidence of Catholicism. Thankfully, although it was my grandmother’s middle name and I was named after her, my middle name is her first name, Frances. I guess that was to make up for being named Jessica, like 2 out of every 5 other girls born in the 80s.
My older sister’s middle name is Marie, my younger’s is Lynn. I got Joy, which is also pretty common I think.
White Americans here.
My wife’s middle name was her mother’s maiden name, as is the Chinese tradition.
Middle name Barbara Ann. I was supposedly named after both my grandmothers, but one was Alice and the other was Anne with an e.
I am also 24. I have an old lady set of middle names. And yes, I know the song.
Niece was born this year, middle name Grace.
Weird. I’ve never noticed this trend, but I’m part of it. I’ve got one of those for my middle name and my sister has another.
I’ve always thought Ann went pretty well with Julia…at least it suits me. 
It’s funny, but almost every Julia or Julie that I know has Ann(e) as a middle name.
My sibs and I were all given more than one middle name (RC, wouldn’t ya know). Two of my three sisters have Mary/Maria as part of their names (with Maria, it’s a first name), two of us have Ann as part of ours. Patricia, Elizabeth and Teresa also figure prominently in my extended family’s middle name scheme.
Elizabeth
My sister and I both have “filler” middle names. If I’d had kids, I would have given them two solid usable names, so if they hated one they could use the other. I’m stuck.
I never use my middle name because it’s far too, oh, fluffy in combo with my first name, but I do use the initial.
Ok, so far the poll shows it’s not THAT common to have those middle names, but the explanations seem to fit my experiences, as I grew up mostly just outside Chicago, and most folks I knew were Catholic.
I also tend to agree with the notion that a lot of middle names are filler, and chosen for the best verbal flow, so something nice and solid works really well most of the time.
Out of us four kids, we have solid, ‘boring’ middle names, but each one was in honor of a person. Except for the ‘Allen’; I’ll have to ask who that was. 
She’d be right. I grew up in Northeast Ohio in the '60s and '70s and most Catholic girls I knew at the time had Marie or Ann as middle names (I put Marie first because it was the most popular - it seemed for every Ann, there were two Maries).
I felt very out of place at times. I’m not Catholic and have a rather unattractive family last name as my middle name - there’s no flow there at all with first or last names. I told no one what it was for years. And then at my high school graduation, it came out. For some reason my full name ended up on my diploma and was announced as I came across the stage. Blech.
Grace is my middle name, and I actually like it better than my first name. Oh well.
I have a lot of friends with Renee or Nicole as their middle names.
My middle name is Jane. I have seven sisters and their middle names are Ann, Kay, Claire, Dee, Jo, Sue, and Jean.
Ours too. My middle name is my paternal grandmother’s maiden name, a fine Scottish name that is very long (and hard for little girls to spell). My sisters all have various long middle names too, some last names, some obscure relatives’ names… my baby sister’s middle name is Evenstar.
Our older son married a girl with the middle name Marie (they are now divorced). She has three or four sisters. For some crazy reason the parents gave them ALL the middle name of Marie.
Does Leanne count as a variant of Ann/e?
