I'm looking for Arthur Emery Robertson anywhere in the state in 1930. He was born in 1913 so would be about 16 or 17 in that census. He and his parents, Charles Arthur Robertson and step mother Agnes were in Covington County, Alabama in 1920. After that I cannot find Arthur. In SSDI his last known residence was Mobile, Alabama. He has a sister named Letie B. Robertson born about 1911 - perhaps she can be found in 1930? I do not know if she was married at that time nor do I know if she ever married. Arthur and Letie's mother was Mattie Adams born in 1888 and died in 1914. Thank you for any help. Melissa
