About Jakob Ignatt
It has been assumed in the family book Ignatius-suku (Helsinki 1942) that Jakob Ignatt would be the ancestor, possibly the grandfather of Jaak Ignat(s)i (ca. 1670-1741), documented in Estonian Wikipedia: http://et.wikipedia.org/wiki/Ignatsi_Jaak . Jaak was assumed to be a son of a "Swedish soldier", who was perhaps a son of Jakob Ignatt.
About Jaak's age was Peeter Ignatzi, a "köster" (precentor, lukkari) in Tartu (ca. 1677-1731) - possibly a younger brother of Jaak. Peeter's son Michael Ignatius (1713-1777) is documented in Estonian Wikipedia: http://et.wikipedia.org/wiki/Michael_Ignatius as also his son David Friedrich Ignatius (1765-1834) and grandson Otto Friedrich Ignatius (1794-1824).
