Joroinen
Joroinen developed as an independent parish in the lake country of Savo around 1630. Its first recorded parish priest, Marcus Aeschilli, held office from 1631. The new parish brought together several tithe districts, including communities associated with Joroinen itself and neighbouring Pieksämäki and Sääminki. Its second church was built in 1685.
Church administration left a growing documentary record of the locality. Parish accounts survive from 1694, registers of births, marriages and deaths from 1695, and communion books from 1725. These records followed households and religious life across the countryside. Eighteenth-century decisions also addressed the duties and support of parish personnel: a district court ruling of 1761 concerned labour obligations, while a parish meeting in 1796 considered the schoolteacher's remuneration. The parish consequently served as a durable local institution linking scattered settlements through worship, record keeping and the provision of teaching.
