The information contained in the profile for Mary Eliza Mather's parents and siblings comes from geni.com, JR Fishburne entry under the name "Mary Eliza Lyons." Sufficient information is provided in the JR Fishburne entry to assure these are the same person. There is still some question regarding her husband's name (Louis Joseph or Joseph Louis). Separate research indicates her father's middle name is Selwyn, not Selwin (as in the JR Fishburne entry). As of Sept 2010, I believe this to be a correct accounting of Gordon Macdonald Mather's immediate maternal family. Note that his aunt Lavilla married A. Gordon Macdonald (that relationship is shown in Lavilla's profile) and is most likely the family source for his own name.
