Hello Juan. My great great great grandfather was Ranulfo Cueva. I have in my possession a book that was written by one of my great uncles. He found a copy of Tomas Cueva's memoirs book, and translated some excerpts from the book. I basically have info about where he grew up, the home and his sister's name, her husband, and her oldest son's names. I also have some information on his grandparents. Please feel free to contact me at email@example.com.
