I'm so sorry for your loss, and I can understand where you're coming from! I've always assumed I would take my husband's name, and in all honesty, I probably will, but the closer I get to the wedding, the more sad I feel about losing my surname - it's a pretty rare surname, and my last link with my late dad. Unfortunately, I have a double-barrelled first name too, so double-barrelling my surname I think would be a bit much!
Funnily enough - I'm becoming a Jones! My fiance keeps telling me I'll need to support Wales in the 6 Nations next year!
There is no correct answer - it's down to you at the end of the day, but keep in mind you don't need to make a quick decision. I'm going to take my time changing everything over - my passport is good until 2026, so I'm definitely not changing that until then!
Also, I think the double-barrelled name for you sounds pretty good!
Good luck with the decision. X
