I am having trouble interpreting a family tree of the Trussell family that I found:

Specifically, near the top right, I see: "WILLIAM = ROHESE dau[ghter] and heir of WILLIAM PANTULF of Cublesdon Staffs: Justice of the Common Pleas 1268". A line goes down and left to "MAUD" in "WILLIAM = MAUD dau[ghter] and heir of WARIN MANWARING of WIRMINGHAM CHES". The line makes it look as though the first WILLIAM and ROHESE are the parents of MAUD, but the text makes me think MAUD's father is WARIN MANWARING. What is the most likely interpretation?
