-Hi!. Is your grandfather from the San Luis Potosi, Mexico area?. If so, maybe the hacienda you are looking for is Hacienda Peotillos. The name sounds very similar to your words. It is located near San Luis Potosi in the central part of Mexico.
Do you have more data on Cresencio Tovar?. My grandmother was Rebeca Tovar Nieto (1894-1962)
