She is the earliest women merchant documented in the history of Finland.
In 1549, Kaarina Multiala is named as "Wife Muldiala", widow of Esko Multiala, and noted to be the wealthiest burgher merchant in Vyborg.
The year of her death is not known: she is last mentioned alive in 1563, but was certainly dead in 1571, when a woman by the name of Elina Multiala, who was likely her daughter, was taxed for her silver.
She was one of extremely few businesswomen documented in Finland at the time, one of even fewer to also pay taxes for her own farm, and the only secular woman in 16th-century Finland to be noted in public records as anything other than a wife.
Kaarina Multiala is portrayed in the novel Kartanonherra ja kaunis Kirstin by Kaari Utrio.
