Joshua Parker, member of Stephen F. Austin's Old Three Hundred colonists, was born on April 13, 1790, in Grayson County, Virginia. He was living in Arkansas in 1821, when he became acquainted with Moses Austin and enrolled in the proposed Austin colony in Texas. He and his colonist partner William Parks received title to a sitio of land in what is now Wharton County on July 24, 1824. Parker's home place on Palmetto Creek was adjacent to Stephen F. Austin's headquarters. The census of 1826 listed Parker as a farmer and stock man, a single man aged between twenty-five and forty. He married Nancy Whiteside in 1828. Evidently he dealt extensively in livestock. He bought a mule from James Gaines in 1824, ordered horses from Josiah H. Bell in 1826, had Austin buy him an ox ring from Nicholas Clopper in August 1826, and had a quarrel with Aylett C. Buckner while he and Buckner were driving a herd of horses from the Rio Grande. In November 1830 Parker was listed among persons who must comply with the conditions of their grants or have their lots sold by the ayuntamiento of San Felipe. He was an acquaintance of William B. Travis at San Felipe in 1833. Parker died on July 24, 1838, at Independence, Texas.
