Margaretha ?: She is in 1678 census as aged 8 years but can't find a birth/baptism for her.
There is also listed in the 1685 census aged 2 an Anna Magdalena - who might be Salomea - a s I cannot find an Anna Magdalena in the baptismal records from 1682 to 1685. (Joe Wolfe Ja n 2001)
My Take (Felix)
If 1678 census is correct we have a twin to Heinrich. Then one would expect that her baptis m is listed too. So I go with the 1685 census and add Magdalena until further notice. If I a m wrong, I hope you won't be too unhappy with your current family, Magdalena. - CHECK
