Sweeny-Waddy Log Cabin. John Sweeny, Sr. (d. 1855) moved his family from Tennessee to Brazoria County, Texas, about 1833. With the help of slaves, he cleared his land and established a large plantation. This log cabin, originally located about 9 miles southwest of this site, was built soon after Sweeny's arrival and housed the slave family that included Mark and Larkin Waddy. The Waddys continued to live in the cabin after they were freed at the end of the Civil War. Recorded Texas Historic Landmark - 1983 #9601
