The Casads moved to the Mesilla Valley in 1874 and became prominent land owners, involved in agricultural, mercantile and newspaper ventures during the late 19th and early 20th centuries.

Edwin Burt was born on March 1, 1868, in East Saginaw, Michigan to Dr. Edwin Burt and Harriet “Hattie” Melville Turner Burt. At age 15, Edwin travelled to the borderland with his father, settling in the Organ Mining District, just east of Las Cruces. Edwin assisted his father with mine inspections and other tasks in the mining field. Dr. Burt’s primary occupation was practicing medicine, but mining lured him to New Mexico, while his wife Hattie and the rest of the family remained in Brooklyn.

After twelve years or so living in Mexico and in Chile, Edwin Sr. and Alice decided to make the move back to the United States from Mexico with their children. The Burt’s purchased a home in El Paso as well worked as a consulting mining engineer.
