I am looking for info on the Brill family, who lived in Hayward, CA (Alameda County) at least as early as the 1920s.

Specifically, I'm interested in:

1) Parents of Walter Leo Brill (married to Georgianna Marenger), lived 1883-1963, born in Kentucky (parents may have both been born in New York, and the mother's maiden name may have been Joeller)

2) Information on Walter's son Warren Leo Brill (born in 1926, married to Joy Sylvia Tuccoli and had a son named Daniel Brill)

3) Information on Walter's son Robert Brill (born in 1923)
