The Cromwells were a generation of witches dating back to the wizard Merlin. Dylan was the first warlock in the Cromwell family, which means that Marvin was either NOT a Warlock, or the family took the surname of the Queen of Halloweentown, as Aggie is referred to as "Splendora Agatha Cromwell" before she is married and not after. The Cromwell family starts with Marvin, the wizard Merlin's cousin. Marvin had Aggie with an unknown Cromwell witch who was Queen of Halloweentown. Aggie had Gwendolyn. Gwen and William had three children: Marnie, Dylan, and Sophie. ==Very small family tree
