Early in the episode, George reminds Martha they are hosting their niece's wedding because they are the only family she has left. It is never specified whether Elinor Donahue's character is biologically related to George or Martha but unless the Wilsons had several relatives pass away since the first season, George's statement is incorrect within the series' own canon.
George Wilson had two sisters, June and Helen, who visited in the first season. Martha also was said at different times to be away visiting at least two sisters (Edna and Elizabeth) as well as her mother. George's brother, John, also appeared late in the third season and was a co-star in the show's fourth and final season. See more »
