Lucy grew up near an unidentified town on Grandpa Dave's farm (inferred as her dad (Grandpa Dave) is said to have lived there for a long time).
Lucy's family attended her wedding.
During a timeout in her room, D.W. exaggerated past events and made them sound worse than they really were; like not being able to attend Lucy's wedding, and being forced to stay home and work as a slave, instead.
Arthur's family once had to spend the night at Lucy's house because of car trouble.
