I show the parents of Mary Alberta to be Walter Clifton Puryear born 27 May 1888 in Graves County and died 23 Oct 1963 in Orange County, California and Mary Ethel Wilson born about 1896 in Kentucky and died 18 August 1921 in McCracken County. I show no other children.
Walter Clifton later married a lady named Birdie. They are in Chicago for the 1930 census. Walter registered for the WWII draft in Chicago (1942). I have no record of any children.
