The mother of Benny was a widow who lived in Benny's hometown.
Sometime in her life, she married a man with whom she had her son, Benny. When he was about ten years old, his father died, leaving his mother a widow, after which time she presumbly raised Benny on her own. She continued to live in their hometown, even after her son moved to River's Edge to get a job working at the local mills, which he was unable to keep.
She married Benny's husband some point in her life, though he died several years afterward, leaving her a widow.
Not much is known about her relationship with her son, but he cared enough about her to wonder how she was doing when he thought she might be in danger.
