Does anyone have a middle name?

No, I've not got one.

My father was the second boy. His mother, my GM, was so disappointed that he wasn't the longed-for girl that he wasn't given a second name. The elder son and the subsequent daughter both had second names. I think my father always felt unwanted and became a bit of a black sheep, refusing to go into the family business and becoming a musician.

I was the last of many children...I think my parents were somewhat weary. My middle name is the same as my eldest sister's first name 🤣

I was raised a Catholic so have a "confirmation" name in addition to my christian name. I don't use the confirmation name as a middle name or initial.
I'm not sure why.

I have a middle name as does DH. The four children I have biologically all have two middle names!

I have two middle names and I have never been accused described as being posh.

I have one, it was my Grandmother's name. Two of my Granddaughters also have it as their middle name.

I have one. It is an old-fashioned name that has been given to first daughters in my mum's side of the family for generations, as either a first or middle name. My daughter has it as a middle name too.

I don't use it often, but add the initial when initials are in use (eg Action Points on minutes) so that there is less confusion.
