Clementine and Olive - my surname begins with a fruit, so these names, and indeed any food/food-related name are out.
DH even put the kibosh on Rosemary (which would have been a great honoring name, as all our grandmothers have/had Rose or Mary either as first or middle names), due to it being a herb, but he did agree to it as a middle name at least.
Cressida was also ruled out, because of the first part of the name, for this same reason.
When I was pregnant with our daughter, I said to my DH, I kind of wish I'd taken his surname when we got married, as opposed to him taking mine (something he wanted, as his former last name, White is very common), because I realized Clementine etc were now unusable. However he then pointed out, that even White wouldn't have worked well, as Clementine White or Olive White, would sound like shades of paint. Ho hum.
