The usual mess ... "their" son Johann Georg Rucker (1607-1661) was apparently born in Bavaria (of course without sources on FS), while the children of "her husband" Wilhelm Conradt (Rucker) Rucken (abt.1577-) are all with sources from "Uiffingen, Boxberg, Baden, Deutschland" (Wikipedia)
I changed the profile to better fit the sources. I assume the connection with Margaret Rucker came from this January 1612 death of a child of her. Maybe somebody can help with a transcript?
