A book on the Lindleys titled: "Jacob Marion Lindley, his Ancestors and Descendants, A Genealogy", by Milam Myrl Ewing, June 1, 1978, names Samuel Washington Lindley on page 11:
"10. Samuel Washington Lindley, born 1788 in SC, died in 1859 in Montgomery Co., TX. Married (1st) Mary (Polly) Elizabeth Hall, June 5, 1809 in Christian Co., KY. She was born about 1789 in Chatham Co., NC, died 1838 in Montg.Co., TX. (2nd) in 1839 in Montg. Co., TX, Eliza Tolbert... (3rd) in 1845 Martha Alphin, a widow." The book does not list Samuel Washington Lindley's descendants.
It lists Samuel as the 10th child of John Lindley and Sarah Baldwin, and names John and Sarah's children as: Simon, William, Mary, John, James, Thomas, Jacob, Jehu, Ruth, Samuel Washington, and Jonathan.
