Martha Ora ?Mattie? Davis was born in Mississippi and moved to Texas as an infant.  She earned a teaching certificate in 1884 and in 1889 married William H. Lucas.  Active in civic organizations and women?s clubs, Mattie spearheaded many civic improvements in Grayson County, including the establishment of a Carnegie Library, home front war work, the collection and preservation of local history.  Her efforts to commemorate the Texas Centennial resulted in the placement of several historical markers.  She co-authored the first History of Grayson County published just days after her death in 1936.
