FAQs

How does the nickname finder work?+

Type a nickname to see the formal names it stood for in historical records, or type a formal name to see its short forms. It searches a curated dataset of US, British and Irish record nicknames both directions — Polly→Mary and Mary→Polly.

Why do old records use such different nicknames?+

Before standardized spelling, clerks wrote the pet name a family used — often unrecognizable today (Polly for Mary, Nancy for Ann, Sukey for Susan). Missing these variants is one of the most common reasons a genealogy search stalls.

Is my search private?+

Yes. The lookup runs entirely in your browser against a dataset shipped with the page — nothing you type is uploaded or stored on our servers.
