Lily of the valley

One of my many favourites Lily of the valley in Swedish called the "Liljekonvalj" and in the name is found also my last name. However, I think it smells bad but probably I am a bit allergic to it for my nose runs and itches if I take it into the house. It makes itself probably better on the range where it grows in the thousands. Can anyone guess where my last name. Ceridwen here it comes.
