Sallie Lankford Howard died of cancer in 1925 and was interred at Forest Lawn Memorial Park in Glendale, CA. The following year, Milford married again to Stella Vivian Harper. This couple reportedly divorced in the mid-1930s. In 1936, Milford began construction on a church back home in DeKalb County, Alabama. The story goes, "He searched his mountain property until he found a huge sandstone boulder that he could incorporate into his chapel, taking literally Jesus's non-literal statement, 'upon this rock I will build my church.'" With the help of the Civilian Conservation Corps, the Sallie Howard Memorial Chapel was completed in June 1937.
Six months later, Milford was dead. He had returned to California and died of lobar pneumonia 28 December 1937 at the Los Angeles County General Hospital. His wish was to be cremated and placed in the boulder that was part of the memorial to his first wife. The second wife, "Lady Vivian," made sure that request was honored.

Former Alabama Congressman Was Colorful Figure
GADSDEN, Ala., Jan. 4 (AP) -- Death has closed the colorful career of Colonel Milford W. Howard, 76, congressman in the nineties from the old Seventh Alabama district and, in more recent years, author, lecturer and promoter.
Friends here had been advised today that Col. Howard had died in California, where he went about three weeks ago to spend the holidays with a son, and that his body would be cremated and the ashes returned to Alabama to be placed in the "Sally A. Howard Memorial Chapel", near River Park on Lookout mountain, DeKalb county, where Col. Howard had made his home.
...He was widely known in his younger days as author of "The Bishop of the Ozarks" and other novels. In recent years, he traveled abroad, interviewing Mussolini and other notables in Europe. He wrote and lectured on his travels, and on psychology and related subjects.
Surviving Col. Howard are two sons, Clyde Howard, Los Angeles, and Claud Howard, Miami, Fla.
Note: There is also a small graveyard behind the chapel.
