I am French.
I research informations about BOU and HOFFMAN families of San Bruno and San Mateo in California.
Prosper BOU (1881-1942) was a french pioneer and a most famous carpenter in San Bruno. I reached to find some newspaper cuts on the Internet, uploaded by a great-grandson's wife of Prosper but I want to know more.
qu'avez-vous deja et que voulez-vous ?
I suppose that you already have:
1920, 1930 & 1940 census - with name & age of children
Burial Place: Cypress Lawn Memorial Park, ... etc
California, Death Index, ... etc
World War II & World War I Draft Registration Cards
Marie Bou Dufroux
Social Security Applications and Claims Index [dates & parents names]
Burial: Holy Cross Catholic Cemetery
I want to complete my genealogical base, maybe this family is eventually on a genealogical base or somebody would have additional informations (descendants, anecdotes, photos...).
In France, every department have a website with civil-status online (with limitations of 100 years for the majority). I don't think so than you have the same in USA and it is more difficult to search genealogy of people who emigrated in foreign country.
If it's not possible, never mind, I've found quite many informations on Familysearch and whitepages.
what you will find here are family trees.
Unless you gather this information yourself [census, acts, directories,... ] you will end-up with a lot of garbage
