Looking for the address of a feed and grain store my great-granddad owned in Riverside,California. His name was Hugh Eugene McNicholl. From what I have been told the store was in the Arlington section of Riverside on Magnolia Avenue. According to my great-grandmother Verna's obit in 1960's they owned and operated it for 40 plus yrs. I'm guessing I'd need a look-up between 1930-1940's??? Can someone please help me. Thanks, Meghan
