Yes sorry not her but another one - Irene Richardson possibly?I don't know where you read this but Marguerite Wall's body was found in the garden of a local magistrate - the house was named Claremont and was on New Street. Farsley which is 11kms from Leeds.
Edit - Jimmy S only had a flat in Roundhay Park not a house.
My source: Wicked Beyond Belief by Michael Bilton which is THE best book on the Ripper as he had direct access to the senior investigators involved (those still alive) and also In Plain Sight by Dan Davies.
