Your name could be a combination of the Spanish names
Juan and David(in Spanish prn duh-VEED). In Spanish, it is very comon that people with first and middle names get called a combination of both. Example of this is
famous Colombian singer Juanes, who's full name is
Juan Esteban. Popular forms of girls names to illustrate this are Marite(muree-TEH), which is short for
Maria Teresa or Marielos(muree-EH-los) which is short for
Maria de los Angeles.
Hope this helps,
