Fred is Scrooges only living relative
His nephew Fred, Fred's wife, and Tiny Tim.
Her name is never mentioned in the original story
Simply to invite his old uncle to dine with him and his family
She says several things, pretty much all of them derogatory to Ebenezer, in Part 3 of the book. She also figures out that her husband was thinking of his Uncle Ebenezer in the game of "Yes or No" at their home.
Fred is the only son of Scrooge's sister Fran, and his only living relative. Fred makes it clear in "A Christmas Carol" that he wants nothing of his uncle, except for his acceptance of an invitation to dinner. Fred knows that Scrooge is his own worst enemy and renews the invitation every year at Christmas. One of Scrooge's greatest acts of contrition and redemption is to finally accept his nephew's invitation, and make peace with Fred's wife.
He feels that marriage is not worth it, having lost his own fiancee due to his greed for money and he has the opinion that his nephew should not have a burden of a wife. Fred points out that he has and always will love his wife. Scrooge's mind changes and he sees Fred happy and content in his life and understands what he himself has lost.
He was continually dislissive citing the Fred should "keep Christmas in your way and I will in mine!"

He would have hoped that Uncle Ebenezer would accept his offer to join Fred and his wife for Christmas Dinner
