Editing Patronymic (section)

====Finnish====
In [[Finland]], the use of patronymics was a result of relatively-recent Swedish influence and remained uncommon outside official documents. It was only in the 19th century that the use of patronymics gained any sort of popularity among the [[Finnish language|Finnish]]-speaking lower classes.<ref name="paikkala">{{Cite web |last=Paikkala |first=Sirkka |title=Patronyymit ja matronyymit sukututkimuksissa |url=http://www.genealogia.fi/nimet/nimi16s.htm |access-date=2 August 2015 |website=genealogia.fi |publisher=Suomen Sukututkimusseura |language=fi |archive-date=24 September 2015 |archive-url=https://web.archive.org/web/20150924040547/http://www.genealogia.fi/nimet/nimi16s.htm |url-status=dead }}</ref> Family names became obligatory in Finland by law in 1920.<ref>{{Cite web |url=https://agricolaverkko.fi/vintti/julkaisut/historiakone/dokumentti.php?id=1283 |title=Sukunimilaki 1920 :: Dokumentit :: Historiakone :: Julkaisut :: Agricola - Suomen historiaverkko |access-date=6 December 2022 |archive-date=6 December 2022 |archive-url=https://web.archive.org/web/20221206074059/https://agricolaverkko.fi/vintti/julkaisut/historiakone/dokumentti.php?id=1283 |url-status=dead }}</ref>

Historically, patronymics were composed in Swedish fashion: the father's name and the suffix ''-n'' for genitive plus the word ''poika'' for sons, ''tytär'' for daughters. For example, Tuomas Abrahaminpoika means "Tuomas, Abraham's son", and Martta Heikintytär means "Martta, Heikki's daughter".<ref name="paikkala" />
