Again, it's fine to interpret the name for yourself this way if you want to. But in terms of historical etymology, you can't just look in a dictionary (of any language) and say that a name means the same thing as words it resembles, without having evidence that the name was created from those words at the time it was first used.
Someone could look in an English dictionary and say that
Ashton would mean "2,000 pounds of burnt wood", but that's NOT its historical etymology.
