California Death Index lists Frank L Granucci with Granucci and Estrada parents. The birth and death dates confirm that he's the same as Frank G Granucci (listed in other databases) child of S & C.

In 1910 census (April 26, 1910), Frank G Granucci is head of household with a wife, aged 30, whose name is tough to read (I think it's Matilde and born in Italy). Also listed are two children, Arthur and Estelle (aged 7 and 3 respectively)

1920 Fed. Census

Ancestry.com (library edition) has 1930 SF census that shows Frank L Granucci (50 - "estimated birth year 1880"), wife Matilda (51), son Frank A (Arthur?) 29, and daughter Estelle B. (23)

Frank L Granucci was a butcher and worked at Palace Meat Market (20719 Jefferson St.) for 50 years (according to his death certificate seen at SF library). Wife was Matilda, born in Italy 1879) and MAY be the Matilda listed in death records as SS# 546-01-2708 and died 3/6/1972. Also listed in death certificate was verification that his mother, Candelaria, was born in California (not Mexico as written somewhere in a census).
