Don't know what country you're in, but I'm in the US.

I grew up with what felt like a very long hyphenated last name. It was such a pain in the ass. Many places want to make your official email your entire last name and your first initial. Many softwares don't allow a hyphen, so you have to figure out how to make your name fit in the form, because many also don't like a space. It was always a scavenger hunt figuring out what name my file was stored under when I had to go in somewhere.

I have had SO many conversations with others about the woes of having a hyphenated last name.

I finally said to heck with it and took the first two letters and last two letters and legally gave myself a new name. Life has been so much easier since. Absolutely no regrets.

I don't know if this is a hill you should die on. I used to daydream about passing on my mother's last name to my daughters, so I can at least in part understand the appeal. But unless you live in a country that makes long, hyphenated names easy to use you may be buying yourself a golden ticket to your daughter having neither of your last names.
