He was the Ruth's father-in-law, and husband to Naomi.
It would be impossible to how Ruth's husband died, without knowing who Ruth's husband was. Last names help distinguish who people are, so without a last name, we don't know who Ruth is.
Ruth's second husband was Boaz. He was a wealthy landowner who showed kindness and generosity towards Ruth and her mother-in-law Naomi. They later married, following Jewish customs.
Tradition states that Boaz (Ruth's second husband) survived only a short time after he and Ruth were married.
Ruth came to know her first husband Mahlon in the land of Moab.
Dr. Ruth Westheimer and Judge Judith Scheindlin are not related.
Mahlon
Naomi was Ruth mother in law, as she was Ruth's husband (Mahlon) mother
