She shook her head.
"I don't know ... just. About twenty. Alf knows; I ain't thought to ask him for quite a while."

"I never had none that I recall. She died early; that was back in Oklahoma, Alf says."
"No brothers or sisters?"
A shake of the head.
"And since then you've been alone with your father?"
