[2] The maiden name of Margaret Luther, the mother of Martin, was
_Margaret Ziegler_. There has been a traditional belief that her name
was Margaret Lindeman. The mistake originated in confounding Luther's
grandmother, whose name was _Lindeman_, with Luther's mother, whose
name was _Ziegler_. Prof. Julius Köstlin, in his _Life of Luther_,
after a thorough examination of original records and documents, gives
this explanation.
