The profile for Martin Keck shows that he and his son Hans died at the same time. This highly unlikely. The husband of Agatha is Hans Keck (1590-1639) and they have 3 children: Magdalena (1630-1689), Martin (1632-1676) and Hans Jacob (aka Johann Jacob) 1637-1682. Please refer to the profiles I created for these people. There is backup information (sources) for most of this.
