What happened to Billy Sunday's children?

Answer 1

ChildrenThe Sundays' three sons, pampered but largely reared by strangers, embarrassed their parents with their errant lifestyles. George was arrested for drunkenness and auto theft before he committed suicide in 1932. Billy, Jr. died in an automobile accident in 1938; and Paul, a test pilot, died in an airplane crash in 1944. Furthermore, their oldest child, Helen Haines, though happily married, developed a degenerative disease and died of pneumonia in 1932.[8]

The boys' ex-wives remained a continuing dilemma for the Sundays. Some blackmailed the evangelist to keep quiet about their son's infidelities. Others used gentler techniques to extract money, and Nell often provided friendly advice to the women when she responded with financial assistance.[9] from wikapidia on Hellen's bio
