There were 2 Peters born at the right time. Felix fit better and the name of the son and potential grandfather matching made a better match but this was not proof. Both of them had the temerity to live to adulthood and marry. I was stuck until I found out about chruch lists. These look somewhat like an 1850 census but with names and ages of all persons in the household.
Some lists however lack the age of the parents.
Fortunately the 1710 list shows the one who married Anna Keller was the younger. To this day I have not been able to find a good probability of Anna Kellers father though I know she is from Zweidlen, a nearby village. The church tax list has Zweidlen as sub category of Glattfelden. I am unsure if the churchbook for Glattfelden is the one for Zweidlen. The reason I know her surname is that Swiss women of this time kept their maiden surname.
