Where can I find this index for Sevoyeta/sevolleta? My Great Grandfather might be listed there as Maxmiano Marquez. His wife's first name was Maria Elena or Mary Helen. I don't have her maiden name. He was a sheep herder. My grandfather (one of Maxmiano's sons) was Dennicio Marquez. All my living family members could remember was names and the town of Sevoyeta "near Grants, NM." I'm just looking for a lead to start on.
