In every biography you read about WMB, you'll find the date of his birth as April 6th, 1909. In his sermon "How the Angel came to me...", WMB relates the story of meeting a medium who said he was born on April 6th, 1909 at 5 am. He told her she was correct.
However... a copy of his marriage certificate to his first wife, Hope Brumbach, filled out in WMB's own hand writing, records that his actual birth was April, 8th, 1908.
