I did find her in kopiot on my second search, but as she is from Juva and this is the only Kardin family likely, and the gap in births from 1731 to 1737, I am putting her with this family. This is correct, she

death from kopiot: “Gårds hu. Anna Kardin u.k.” dies of heart attack at age 27

this death could be wrongly attributed. There must be more than one Anna Kardin, for a soldier Mich Hoffberg and Anna Kardin have son Anders in Soiniemi on 17.1.1765, a Michel Hännin and Anna Kardin have son Michel in Pohjois on 20.10.1771, they have Daughter Maria in same place on 13.12.1774, and son Johan in Pohjois in 1781, maybe others.

A “trp. ea,” Anna Kardin dies on 28.2.1791 in Pohjois, Juva of “lifsjuka” at age 53, therefore born about 1738
