Hello Cesar: I'm sorry I don't speak Spanish very well so I will do my best to write in simple English for you. My name is LaMar Ynostroza Mendiola. I live in Houston, TX. and I just started my account with Ancestry.com and found your message. I have heard and read about everything you said about the Ynostroza or Inostroza families and I know the ones who spell their name with Hi or I, mostly come from South America. Over the years I have met some people here in Texas who spell the name with Hi and even have some distant relatives who spell it that way too but they are from Mexico. Some of my other distant relatives spell it with -SA or -ZA but we are still related. I also have read about the "Ville" Inestroza in Spain that I found here on the Internet in a historical Spanish book. Write to me sometime so we can compare notes if you want. I would like to know which of my Spanish relatives arrived in Mexico first! Take care y hasta luego...LaMar Ynostroza Mendiola
