Margareta Henricsdotter Marjaniemi (Niinisalo) (circa 1667 to March 01, 1747) is shown as the mother of Antti Jaakonpoika Marjaniemi (September 30, 1689 to February 01, 1771) [Margareta Henricsdotter Marjaniemi].
Marketta Heikintytär Marjaniemi (circa 1667 to March 01, 1747) is shown as the mother of Maria Matintytär Marjaniemi (1692 to December 10, 1761) [Margaretha Henricsdotter Mantyniemi].
Judging by the same birth/death dates being used for the above two women, and since ‘Marketta Heikintytär’ and ‘Margareta Henricsdotter’ are the Finnish/Swedish equivalents of each other, it appears that the above two women are one and the same woman.
Which is a problem because Antti Jaakonpoika Marjaniemi and Maria Matintytär Marjaniemi are husband and wife.
