Margareta i Kumla, (Floruit 1628), also called the Sibylla of Kumla ("The Prophetess of Kumla"), was a Swedish visionary, who claimed to be obsessed. She became the target for pilgrimages when claiming to be the channel of the words of the angels. Margareta was born to Johannes Laurentii, who was since 1619 the Vicar of Kumla. In 1626, she is described as a teenager. That year, she said she had visions of a white bird and a black man. The black man tried to convince her to abandon her beliefs. At the same time, both the vicarage and the church begun to experience the phenomena of poltergeist.
