Philippine Sophie Caroline Luise Rosalie (Rosa) von Roeder Kleberg, Texas pioneer, daughter of Lt. Ludwig Siegismund Anton and Caroline Luise (Sack) von Roeder, was born on July 20, 1813, at Vorden, Westphalia, one of eleven children. She was probably reared at the family estate, Marienmünster, near Höxter, Westphalia, in a household of affluence, where her major occupations were playing the piano and doing fancy handwork. Her acquaintance with Robert Justus Kleberg resulted from her brother's attendance at Georg August University, Göttingen, where Kleberg was also a student. When her father's fortune faded, the family decided to emigrate to Texas, influenced by letters from the German settler Johann Friedrich Ernst. Rosalie persuaded Kleberg to go with them, agreeing to marry him only if he consented to move to Texas. Their wedding took place on September 4, 1834. The entire Roeder family left their homeland in two expeditions that year; Rosalie and Robert Kleberg left with several others on the second trip, sailing on September 30.
Mrs. Kleberg's ability to adapt developed rapidly in Texas in response to repeated trauma: a shipwreck on Galveston Island, crude living conditions, the Texas Revolution, postwar unsettlement, and the deaths of family members. Within months of their settling at Cat Spring the revolution began. In the fall of 1835 Rosalie's brothers Albrecht and Louis von Roeder joined the army and fought in the siege of Bexar. Louis and Rosalie's husband Robert fought in the battle of San Jacinto while Rosalie fled with an infant child and other family members in the Runaway Scrape. When they returned they found that Mexicans had burned their homes and fences and most of their possessions. Rosalie recalled afterward that they were forced to start again with less than they had as new settlers.
When numbers of German immigrants began increasing following the war, Mrs. Kleberg showed sympathy to those, some sick and dying, who came by her home on the way farther west. One of her guests was Prince Carl of Solms-Braunfels, who requested coffee from her but refused to sit at the same table with others. She refers to him as a "conceited fool." Her dress, a youthful European stylishness in the 1830s, gave way to fashionless, functional attire, while her love for farming and country life moved her to build chicken houses like log cabins and to plant her garden in curved rows. In 1847 the Klebergs moved to Meyersville, DeWitt County, where they reared to maturity seven of their eight children, plus several nephews, grandchildren, and a foster son. Rosalie Kleberg survived her husband by twenty-seven years. She died on July 3, 1907, in Yorktown, Texas, and was buried on the Caroline and Robert C. Eckhardt ranch there. She was survived by three daughters and three sons, one of whom, Robert J. Kleberg, married Alice Gertrudis King and assumed management of the King Ranch on the Texas Gulf Coast.
