Hi Luke, Was able to gather a little from ancestry old newspapers. Fresno newspaper.
Forrest's father, Bert, was killed in a car-train accident in Tulare Co. 1951. The family sued the RR, but only got a small settlement.
Daughter, Marlene married Richard? Gordon 1953, she was 17, he was 19 and going into the Navy. There are several Gordon/Gardner combinations on CABI, but these are the most likely (just guessing) Kathy A - 17 Mar 1954 San diego Co, Cheryl A 13 Mar 1956 Tulare Co, Michael L 9 Dec 1958 Tulare Co.Pretty sure Marlene remarried 1971 to Wesley Hansen.
From Tulare Co. gen websitehttp://usgenweb.org/states/index.shtmlhttp://usgenweb.org/states/index.shtml Smith Mt cem Bert and Mildred Gardner Forrest and Ruby their daughters, Ethel 1939-1954 Judith/Judy 1945-2011
Their son on 1940 census is listed as Billie J. So he has been hard to find.Don't know if he would go by Bill, Billy, William.
You can always try the Library or newspaper. There is a link on the Tulare Co site.
