At least one child
When Joyce and Irv were having trouble in their marriage, they went to see Ben Barnes for counseling. He encouraged them to make romantic gestures, saying that even if you know your partner loves you, it's nice to be reminded once in a while. He later saw them at the diner and Irv surprised Joyce with a flower.
He is married to Joyce. They have at least one child together, who was conceived before they were married. When they started having trouble in their marriage, they went to see Ben Barnes, who helped them recapture their love.
He has at least one child with his wife, Joyce, which is said to be the reason they got married in the first place.
Ben was Joyce and Irv's marriage counselor.
