Allen K. Ruoff was born in Texas, but, by 1910, had moved to Los Angeles, CA, with his mother, step-father, and two step-brothers. He died in Los Angeles County, CA, at the age of 51; the certificate of death is given in the LAPL California Index as 11/15/1945, not 11/09/1945, as Henry Withey reported.

His mother was named Mattie (born c. 1873 in TX); she apparently married at least three times; her children had the last names Howell and Ruoff, and she was married also to Ruoff's step-father, Clay D. Wilkinson (born c. 1877 in OH).

His mother's maiden name was Lawrence;

According to architectural biographer, Henry Withey, Ruoff specialized in houses, but also designed the Wilshire Branch of the Los Angeles Public Library; Ruoff penned occasional articles for the Los Angeles Times on the art of house design in the 1920s. SSN: 550-26-2209;
