congratulations on your site!
i am a portuguese 20-year old,from the island of madeira.i am curious to know the origin of my maternal grandmother's surname - "tranquada". no-one in the family knows where it comes from, and it certainly is an unusual surname in the portuguese language.i have searched the web and only found the name "tranquada" regarding people of my own family. if you could tell me where my surname comes from, i would appreciate that very much.
