[Texas] Dunlap, William Walradt, Archive of Letters from William Walradt Dunlap, from
Brownsville, San Antonio and Goliad, Texas to his cousin Jane C. Dunlap, 1847-1861. Archive of 59 letters, totaling 172 pages, from William Walradt Dunlap to his cousin Jane, in Cherry Valley, Waterville, and Norwich, New York. (Also includes three letters from Dunlap to his uncle Robert Dunlap). Highly interesting collection of letters from William Lipe Walradt, of Utica, New York, who later changed his "jaw breaking" name by legislative act in 1849 to William Walradt Dunlap. Dunlap was a lawyer, and a Mexican War Captain, organizing and recruiting the 10th Regiment of Infantry, his unit was based near Matamoras, he became enamored of the area and returned in the fall of 1848 and was one of the first settlers of Brownsville, where he was a lawyer and County Clerk, and commanding Major of the Brownsville Volunteers, Texas State Representative, Mayor of Brownsville. Dunlap later moved to San Antonio before settling on a large tract of land he had purchased near Goliad, with his family and slaves. Dunlap was clearly interested in his younger cousin and the attraction seemed mutual, however he moved to Texas and refused to return North. The two eventually married others. Dunlap eventually became a ―Southerner and a slave owner and planter, he took up the cause of his new home upon the secession of Texas and served with the Confederate forces as an officer and was active in home defense. The letters describe the early development of the Brownsville area by one its earliest settlers, and the settlement of the Rio Grande valley. Dunlap spent much of his Mexican War service as the chief Judge of the Military Commission of Matamoras and on returning to the area continued his legal practice in Brownsville. Dunlap went on to play a role in the political life of his town and adopted state, serving in local and state government. He had by 1861 become a Texan and when war came was loyal to his adopted state and sided with the Confederate cause. The correspondence ends abruptly in April 1861 cut off by the war.
