Since posting this query, I found the family in the census of 1920 and 1930. The Daviess Co., Ky., census of 1910 has the name as EARL HEAD, age 21. The 1920 Census of Vanderburgh Co., Indiana, has the name as JOSEPH E. HEAD, age 31. Still in Evansville in 1930, only the head of household is wife Margaret, age 36 and now divorced. Have not located the husband, JOSEPH EARL HEAD in 1930. Names of the children: Katherine, Edwin, William, Raymond, Delbert and Ruth. Would like to locate descendants.
