The 1910, 1920 and 1930 censuses show us that Mildred's parents are Jim Lawhorn and Bertha Olinger, and she has a sister Erna b. c. 1904, Kansas, and a brother, Marion, b. c. 1907, Kansas. These siblings would be aunt and uncle of our James.
Marion married Lora Elsie Taylor and was living in Gray County, TX in 1930.
