FAQs

How many historical nicknames are in this list?+

468 nicknames, mapping to 629 formal given names. Each row carries the era the nickname was in use and the regions it is attested in, because a pet form that meant one name in 1790s Scotland often meant another in 1880s America.

Why do old records use nicknames so different from the formal name?+

Three habits account for most of it. Rhyming forms replaced the first sound (Mary to Polly, Margaret to Peggy). Clerks wrote down whatever the family said aloud, so the household name reached the page instead of the baptismal one. And some pet forms drifted so far they look like separate names now, which is why Nancy standing for Ann surprises people.

Can one nickname stand for more than one formal name?+

Often, yes. Where a nickname has several candidates, this list orders them by how commonly the mapping appears in records, most likely first. Treat the later ones as leads to test against a date and a place rather than as equal answers.

Where does this data come from?+

It is a compilation of individual factual mappings drawn from genealogical and onomastic reference material, then checked row by row. Provenance and method are documented in the dataset's own sources file. Nothing here is generated by guessing at a name.
