John Ekin Dinwiddie was born in Chicago, IL, on 10/27/1902.

In 04/1910, the Dinwiddie Family lived at 177 Franklin Street, Bloomfield Township, NJ.

Ten years later, it had moved to CA, living in a residence it owned at 2943 Avalon Drive, Berkeley, CA; according to the US Census of 1920, the family employed an 19-year-old Irish cook, Grace Dooney at this time. In 1956, Dinwiddie lived at 9412 Stroelitz Street, New Orleans, LA 70118-1944;

He was buried at the Alta Mesa Memorial Park in Palo Alto, CA.


His parents were William Stewart Dinwiddie, (born 08/16/1871 in Clarksville, TN-d. 12/13/1932 in San Francisco, CA) and Helen Starrett Dinwiddie (born 04/14/1872 in Lawrence, KS- d. 08/22/1962 in Contra Costa County, CA). Her parents came from PA, his from VA. They married c. 1895.

William S. Dinwiddie founded the Dinwiddie Construction Company in the San Francisco Bay Area in 1911. (In the wake of the San Francisco Earthquake of 04/18/1906, abundant construction work was to be had in the Bay Area.) In 1920, he held the title of Dinwiddie Construction's President. Throughout the course of the twentieth century, it would become one of the largest construction firms on the West Coast, before merging with the E.A. Hathaway and Company construction firm on 10/01/1996.

John had four brothers: William Starrett Dinwiddie (b. 1896 in LA-d. 1928), Goldwin Carrington Dinwiddie (b. 1898 in LA-d. 1957), James, (born 01/04/1908 in Berkeley, CA-d. 1994) and William Stewart Dinwiddie (born c. 09/1915 in OR-d. 1966); four of the five brothers had been born in different states, indicating that the family moved a great deal. It is likely that William S. Dinwiddie's construction projects forced this periodic relocation.


He married twice, first to Frances Fredericka Matthews Dinwiddie Keating (1904–1993) in 1939.

He then wed Evelyn Sanderson Dinwiddie (1899–1987), in 1955.

Biographical Notes

John and his brother, James, traveled from London, UK, to New York, NY, between 05/05/1928-05/14/1928 aboard the S.S. Minnewaska. Both lived at 2815 Oak Knoll Terrace in Berkeley, CA, at the time.
