Descendants of John Garr

I am looking for information on the Garr family. Surnames in our family tree include Sullivent, Wall, Berry, Marchbanks, Norris, Qualls, and Mansfield. Most of our family was located in Arkansas, Kentucky, Tennessee, and some in Missouri.
In particular, I'm looking for information on Elkanah (or Elcana) Sullivent d. 1884, Zephaniiah Berry d. 1879, William Marchbanks (born in S. Carolina) and his wife Milly (born in Tennessee), William James Qualls and his wife Lillie M. Mansfield. I have no information on William or Lillie's parents.

Also, I am beginning research on the Lawson family. Surnames include Simons and Owens. Many of the Lawson's were located in Mississippi. I cannot find information on Charlie Lawson d. 1933 or 1934. He was married to Nettie Esterlee Owens.

Any information would be appreciated, and I will share any information that I have.
