"On his way home from the dance, at age forty [Dec. 31, 1879], he [Frank Chapman] collapsed and died of gastritis. ...Only six days after his death, Andres Dold returned to Las Vegas from New York. He immediately began... discovering and arranging Chapman's estate. ...Two days after Chapman's sudden death and three days before Dold arrived, Marcus Brunswick, a long time associate of Dold, and Chapman's nephew, John, petitioned the San Miguel County Court for appointment as administrators of Frank Chapman's estate. ...Five days later, one day after Dold's return, there appeared in the county courthouse for the first time two partnership agreements between Chapman and Dold, one dated 22 November 1873, and the other dated sometime in February 1879, but both filed 8 January, 1980. The 1873 agreement provided simply that Frank Chapman would continue Andres Dold's previous business under his own name. The two men would share equally the profits and the losses... The 1879 agreement... added that the two men would share as "equal partners and joint owners all real estate held and possessed by said Chapman..." including the Pecos grant."
