Col. James Edmond Saunders' EARLY SETTLERS OF ALABAMA (New Orleans, 1899) contains biographical information about Dennis Lindsey and his father Mark Lindsey (pp. 122-123). Saunders writes, "Mark Lindsey was a tall, spare, old gentleman, who lived on a branch of Flint river when I first knew him. He wore the round-breasted Methodist coat, and had a most excellant [sic] reputation. He was also noted for his industry and good morals. The venerable Mr. McFerrin rode this circuit when quite a youth, and still remembers and speaks of the kindness and hospitality he received from the Lindseys. Mark Lindsey was raised in South Carolina. He went to Kentucky when young, and lived there a long time. In 1827 [sic] he and his son Dennis (who was a second edition of his father, in person and character), came to Lawrence county, and settled in the place I have mentioned" (pp. 122-3). Saunders goes on to talk about the Speake family, noting that Dennis Lindsey's daughter Sarah married J.B. Speake, who represented Lawrence Co. in the AL legislature; Saunders also notes that J.B. and Sarah Lindsey Speake were parents of Henry Clay Speake, Chancellor of the Northern Dist. of AL, and later Judge of the 8th Judicial Dist., and Daniel Webster Speake, also a judge and a member of the AL legislature. (Note that Saunders spells the name "Speak," whereas the family uses the spelling "Speake").

The family cemetery in which Dennis, his wife Jane Brooks, and his parents Mark Lindsey and Mary Jane Dinsmore are buried is on what was Dennis's farm at Oakville, Alabama, a town he helped to found. When the town was incorporated by act of the AL legislature on 9 Dec. 1833 (Act 8, Acts 1833, p. 57), Dennis Lindsey was one of the three town commissioners (with William Hodges and Samuel White) who laid out the town and held an election for officers.
