I'm getting married in July and I'm keeping my maiden name but adding my partner's name to make my surname double barrelled. I was never really keen on double barrelled names but I am really close to my grandpa and he's been my dad pretty much all my life and I am the last 'kid' left in my family with the name since my mum is now married and has a new surname and I'm an only child so I wanted to keep my original surname for homage to my grandpa but also take my partner's name and I feel like by taking both names, I am still remaining a part of my birth family yet also gaining in a place in a few family.
There's no right or wrong thing to do when it comes to changing your name when you ger married, I personally believe it should be up to the person who intends to change their name or not, which is usually the woman (when it comes to heterosexual relationships at least) and they should never be pressurised into taking a name if they don't want to. My partner was ok with me changing my name or not, he wasn't fussed either way.
