José María Ontiveros was my greatgrandfather, he was borned in Mérida, México somewhere around the last decades of 1800s. He moved to Argentina, and started a family here. One day, he just desapeared. Noboby heard of him again. We think that there could be a chance that he moved somewhere else, and start a new family, or had anothere family before. Anything anyone can tell me will be very usefull to understand more about our one history as a family.
