Niddy

Niddy is not a name with a long, independent historical lineage. It primarily functions as a diminutive or pet name, often derived from more formal names such as Ann, Anne, or Agnes. The practice of creating 'n' diminutives (e.g., Nan from Ann, Nelle from Ellen) was common in medieval and early modern English, and 'Niddy' likely emerged from this tradition as an affectionate, informal variant. Its usage would have been predominantly within families or close communities rather than as a formal given name.
