Amanda Fallier von Rosenberg, whose letters picture immigration to and life on the Texas frontier, was born at the Carolinienhof estate, East Prussia, on September 6, 1806. She was a well-educated woman who grew up in a cultured and refined household. Her family is believed to have been descended from the ancient family Fallieri, of Venice and later of France. At the age of twenty-four Amanda married Peter Carl Johann von Rosenberg, a lieutenant who served in the Uhlan lance cavalry under Gen. Gebhard Leberecht von Blücher at Waterloo, and moved to his estate, Eckitten, in East Prussia, where she reared his three children by his first wife. Amanda and Peter Carl themselves had five children and later adopted the niece of his first wife. The Rosenbergs, aristocratic by heritage and democratic in their political philosophy, professed the sentiments of the freethinkers. Eventually, they found life in Prussia increasingly oppressive. When their grown sons, Wilhelm, an architect, and Johannes, an engineer, were forced to resign from their posts in the Prussian government, the family decided to leave Germany. They sailed from Bremen on October 1, 1849, on the Franziska and after an ocean voyage of eight weeks landed in Galveston, Texas, on December 9, 1849. They purchased 800 acres and the house of Nassau Farm in Fayette County, where they lived, with their married children settled nearby, until 1861. Then they moved into Round Top, where Amanda died in April 1864. She was buried in Soergel Hill Cemetery, now known as Richters Cemetery, near Round Top. Her prolific, diary-like letters give a fascinating first-person account of the Rosenbergs' trip to Texas and their early life there. Most of the letters were written to her sister-in-law, Johanna "Hännchen" Fallier at Carolinienhof, and to her dear friend Reverend Theil in Memel. Her descriptions of Texas frontier life included information on foods, farming methods, architectural styles, rural economy, and the social customs of the Germans who settled in Texas during the 1840s.
