Very little information is known of Marcos Carrisalez. He appears on the 1870 Eagle Pass census living in the household of Rita Alderete and her mother. He does not appear again until 1910, again on the Eagle Pass census census, living with Francisco and Jesus Garza.
Refugio San Miguel, Trinidad San Miguel's son, told me many years ago that Marcos was the foreman of the ranch and was well respected and loved by everyone in the family. It is my personal opinion that Marcos lived at the ranch from the time it was built (1873) until the time the land was leased to J. K. Burr in 1905. That would explain his absence on censuses between that period of time.
If anyone has additional information on Marcos we would like to hear from you.
