Do you know the denomination of the church of which Ray Edward POWERS was a minister? If so, the church should be able to help.
The E. would match Ray E. of Marion Co., Iowa, 1930: POWERS, Charles E., b. ca. 1869; Mary M., 1874; Ruby, 1903; Cecil D., 1909; Ray E., 1914; Helen M., 1916.
Social Security Death Index has several Cecils. The most likely match seems to be Cecil POWERS (24 May 1908 - Oct. 1975), last res. Des Moines, IA.
