Family History

I've been doing a little family history research lately. This all started when I came across my dad's silver and turquoise ring that he bought out of the Trading Post he worked at as a young man. So of course I had to find out which Trading Post it was.
I knew he had worked at a trading post on the Navajo Reservation, but on questioning my mom, I found out that right out of high school, he worked at Towaoc at the Ute tribal headquarters. He spoke Ute very well, and acted as an interpreter for the tribe. He was also the Assistant Postmaster at this time. He purchased a pair of beautiful beaded gloves there in 1938 or 1939. We still have them, and they are in excellent condition. They have beadwork roses on the back of the hands. It is the plan to return them to the tribe when my mom passes on. I figured I would personally deliver them so I could spend a little time in the four corners area where my family lived. The trading post is gone now but the Utes still have their Headquarters in Towaoc. The gloves are exceptional and belong in a museum.
In the early to mid 20th Century my Grandfather was farm manager for a Boarding School in Waterflow New Mexico, so this same train of thought got me to wondering about the school. My search turned up the Sacred Heart Academy in Waterflow. I doubt there was any other Catholic Boarding School in the area, so this must be the place.
Included in the short history of the school was a picture of the students in 1928. I figure my dad and a couple of Uncles should be in the picture, but I haven't seen enough pictures of my dad as a child to pick him out. The school was run by the Ursuline Sisters, who have an active web site. I have sent them an inquiry about Grandfather and the students in the picture.
