The Laguna Seca Ranch was initially established in the year 1867 by Macedonio Vela Senior and his wife Mercedes Chapa Cantu.

Approximately ten years earlier, Macedonio Vela Senior fled from Mexico to escape the wave of executions associated with the War of Reform.

In 1867, he purchased one square league (4,428 acres (18 km2)) of the Santa Anita Land Grant from John and Salome Balli McAllen.

In recent times family members manage the ranch holding, although it is subdivided into three tangent parcels.

In 1871, Vela's daughter, Carlota, grew the first orange trees in Hidalgo County from the seeds of a fruit given her by a traveling priest.
