Jokosta

Jokosta is a Finnish-language surname. It is typically treated as toponymic, arising from a place name or geographic feature associated with a river. The root element is likely related to joki, the Finnish word for river, with the -sta suffix indicating origin, or a locality name incorporating that root. As a result, Jokosta would historically designate someone from a place called Jokosta or a nearby riverine area. The surname remains relatively uncommon in Finland, and it does not feature prominently in major biographical reference works.

In genealogical records, bearers of the name may appear in civil and church registers dating from the late 19th and early 20th centuries, often concentrated in Finnish-speaking regions. Outside Finland, occurrences of Jokosta are rare and typically reflect migration or diaspora. The name is not widely associated with any widely known historical events or organizations.

Notes on Finnish surnames suggest that many similarly formed names arose through local toponymy and settlement patterns in the 19th and early 20th centuries. Jokosta thus exemplifies a regional toponymic surname common in Finland, even when it remains uncommon overall.
