Talley, deeply religious and a member of New Jerusalem Missionary Baptist Church in Inkster, was often asked her secret to living so long, and her answer remained the same over the years.
"She always prayed that she should not suffer," her longtime friend Michael Kinloch told the 'Detroit Free Press'.
"God certainly answered her prayer," he said.
Talley was born in Montrose in 1899 and moved to Michigan in the 1930s. Her husband of 52 years, Alfred Talley, died in 1988 at the age of 95. They had one child.
Talley led an active life and went fishing every summer. She gardened and mowed the lawn late into her life and bowled until she was 104.
