He was a veteran of the Battle of San Jacinto and the brother of Louis Kleberg.  He arrived in Texas in 1836 with his wife Philippine Sophie Rosalie "Rosa" von Roeder, who was a child of the at one-time aristocratic von Roeder family, which was allied with the wealthy and aristocratic Sack family of Nordrhein Westphalia. Robert and Rosa had eleven children, seven of whom lived to adulthood; Clara, Johanna, Caroline, Rudolph, Marcellus, and Robert II (commonly known simply as Robert).
 
He is the namesake of Kleberg County, Texas.  His sons also achieved success.  Rudolph Kleberg (1847-1924) became a United States congressman, Marcellus Kleberg (1849-1913) studied law and served as city attorney for Galveston, Texas, and the youngest Kleberg son, also named Robert Justus Kleberg (1853-1932), managed the King Ranch and later married Alice Gertrudis King, the youngest daughter of cattle baron Captain Richard King.
