Peter's 'wife was probably Anna whose death is recorded in the same church register in the year 1683 as follows: "11 August, Anna Fahrenstuck, Witwe (widow) ihres alters 70 jahre" (aged 70).'
The author has mistaken the year of Anna's burial. The event is recorded in the year 1688.
↑ Birth year estimated based on age at death (70, which may have been approximate) and on approximate birth year of her son. Alternately, she was born about 1618 and was Wennemer's step-mother.
