In my records I have a family that lived in San Joaquin County. The 1920 census says they lived in Elkhorn, all other records, 1918 draft registration, 1930 and 1940 census, say Lodi. The address is the same throughout the records. Why is the town called Elkhorn one time and Lodi the rest of the time? Nancy in Louisiana

Believe that's Elkhorn Twp in the town of Lodi. Barbara
