Edwin Oswald LeGrand, soldier and signer of the Texas Declaration of Independence, was born in North Carolina on June 28, 1801, the son of John and Margaret (Chambers) LeGrand. He married Martha McGehee in North Carolina in 1825 and in 1833 moved his family, consisting of a son and a daughter, to the Ayish Bayou District of Texas, now San Augustine County. On May 11, 1835, he received a land grant from the Mexican government. During the Texas Revolution he is said to have served under Capt. George English at the siege of Bexar, but his name does not appear on English's muster roll or on the list of those who received donation certificates for participating in the storming of the city on December 5–10, 1835. In February 1836 he was elected with Stephen William Blount and Martin Parmer as a San Augustine delegate to the Convention of 1836 at Washington-on-the-Brazos. He reached Washington on February 28, the day before the convention began, and began to lobby energetically for independence from Mexico. On March 1, the opening day of the convention, he nominated for secretary Herbert Simms Kimble, who was easily elected. On March 3 LeGrand was appointed to the committee on privileges and elections and to a committee of five "to inquire into the actual condition of the army." He signed the Declaration of Independence on March 2 and the Constitution of the Republic of Texas on March 17. After the convention adjourned, he enlisted as a private in Capt. William Kimbrough's company of Col. Sidney Sherman's Second Regiment, Texas Volunteers, and took part in the battle of San Jacinto. From 1836 to 1838 he served as chief justice of San Augustine County. On November 18, 1839, he was elected inspector of the Third Brigade of the Texas militia. Nothing further is known about his family. From 1846 until his death in 1861 he lived at the home of his sister, Mrs. W. C. Norwood. He is buried in the Macune Cemetery, twelve miles south of San Augustine. In 1936 the Texas Centennial Commission placed a historical marker at his grave.
