Thanks so much David, very very helpful. Sorry for the misleading tittle, but it is definitively a martlet, and a mural crown. Toy/Toye or Sewel families have the same family crest. (admin edit - see Posting Requirements )
Then the mural coronet in both of this crests have 5 towers (meaning town?), and the one I have has 3 (meaning village?). I don't know if this is makes it a different family crest, but getting closer.
