The Country Club was founded in 1904 and the street was named to reflect the club. I spoke to a local builder who has history in the area and he is not aware of a 1000 acre Almond Ranch in the area. Additionally the City of San Gabriel has a section on their website http://www.sangabrielcity.com which indicates which streets have had a name change and neither Country Club nor Roses are on the list. Perhaps it is another area. Best wishes on your history hunt.
