How does Darby O’Gill and the Good People develop the theme of Family and Loyalty?

Darby O’Gill and the Good People by Herminie Templeton Kavanagh develops Family and Loyalty across the chapters the companion marks for this theme.

Despite their quarrels, Darby's loyalty to his wife, children, and neighbors is evident, as is the importance of family lineage and reputation, with characters fiercely defending their kin and seeking to protect their households from harm.

The Caseys' desperate longing for a child and their plan to adopt secretly underscore the central theme of family and the pain of childlessness.
