Actually I found a thread from 2006 that I initiated and got some great assistance and information, including the following.

Bobby Blue Bland was born Robert Calvin Brooks. He later took his father's surname Bland according to his biography on Malaco.com.

On the Shelby, Tennesee 1930 census I located one Robert Brooks age 3/12.

What I am trying to find is the father but may not ever know unless I get it from Bobby. Ironically, the names in his household were Brooks and Smith. These names are on my mother (Smith) side down in Coffeeville, MS, and my mother married a Bland. Since the Memphis area was the first migration stop north of Mississippi, I am guessing that the Blands, Brooks, and Smiths made their way up to Rosemark, outside of Memphis, as they did to Chicago.
