My maiden name was relatively rare, but easy enough to spell etc - I had no great desire to hang on to it and adopted my husband’s name without even thinking of not doing so.
But teenage me always wanted a surname beginning with a B, as I loved signing the letter B! So I always imagined fancy surnames like Baudelaire, or even a standard Ballantine.
Now, if I were choosing, I think I would go for something a bit quirky - I dunno, Midwinter or Evensong or something.
