I think the mother's name is Johanna GUSTAFSDOTTER. Is Skyas correct for the place? What does the 51 refer to? I believe the mother was 41?
The fathers name is Swensson Swening and the mother Gustafsdotter Johanna, Skyås is the place, the mothers age was 41 and the number 51 reffers to the page in the book "Husförhörslängder". I don't know if you know what "Husförhör" was, but from 1686 to the end of 1800 the priests held an annual interrogation with every household to check their biblical knowledge. This was called Husförhör (house interrogation)
