I could find only two by the name Eugene Ruiz in the 1930 Federal Census on Ancestry, both born in and residing in California. The following was found for a Eugene L. Ruiz, age 6. Perhaps he came to Kentucky before joining the service. Dan A. Ruiz, Head Auto Mechanic, age 32 Julia R. Ruiz, wife, age 29 Geraldine E. Ruiz, dau., age 9 Eugene L. Ruiz, son, age 6 William L. Ruiz, son, age 3 Louise M. Purio, sister-in-law, age 20 Dan was an auto mechanic. All were born in California as were their parents. Source Citation: Ancestry.com.
