In letters and diaries written in a period from 1730 to 1774, Father Calahorra documented the locations of native villages, their populations, customs and lives as well as mapped the territory of the Spanish colony of Texas.
Father Calahorra not only provided historians, archeologist and anthropologists with valuable information about the native tribes of Texas but also the workings of the Spanish government in North America and the missionary period of the New World.
On Saturday, September 19, 2009, the Old Dallas-Shreveport Road Preservation Association will dedicate an official Texas State Historical Marker to honor Father Jose Calahorra for his significant contribution to the early history of Texas.

Dedication ceremony for this historical marker will take place in Edgewood, Texas at 2:00 p.m. at the Cheatham Memorial United Methodist Church Fellowship Center located at 205 South Houston Street. Scheduled speakers will include State Representative Dan Flynn, Van Zandt County Commissioner Ricky LaPrade and Van Zandt County Historical Commission Chairman Lawrence Greer. Special guest speaker will be Most Reverend Alvaro Corrada, S.J., Bishop of the Tyler Diocese of the Catholic Church.
Refreshments will be served prior to the ceremony and, following the ceremony, a caravan will travel to the location of the marker on Van Zandt County Road 1117 for the unveiling. Everyone is invited to attend this momentous occasion that is the first to mark 18th Century history in Van Zandt County.
