If you know where Vidal and/or Ramona Nunez were from or born you could try and contact the perish(s) in the area and ask to see if they have baptismal records, which would show their parents names, ofcourse you would need to have an idea as to the year. Now Ramona could have immigrated from Spain as Nunez is from Spain. I'm a Nunez and my Grandfather Nunez immigrated from Spain. I hope this helps you a little. I hope you find what you are looking for. Good luck.
