Hello: I'm from another branch of this family. Elizabeth L. Mather is my great grandmother. My grandmother is Adrienne S. Ziegler (b: 1892), daughter of Charles W. Ziegler and sister of Charles W. Ziegler, Jr. (b: 1895) and Alfred Mather Ziegler (b: 1894)
Elizabeth also had two older siblings: Joseph Shiloh Mather (1862-1937) and the wealthy industrialist Gordon Macdonald Mather (1867-1955) of Toledo, Ohio (born at Belle Alliance, St. James Parish). I am named for Gordon Mather (a great-great Uncle). Adrienne S. Ziegler married Dr. Willard James Riddick.
Also, Elizabeth Mather is decended from James Mather, the 4th mayor of New Orleans, whose son, George, had 8 children, one of whom is Louis Joseph Mather who married (1) Mary Steer Peirce, and (2) Mary Elizabeth Lyons.
I would be happy to exchange information on the family connections since we appear to be cousins and my information on the Ziegler side of the family is incomplete.
Thanks, Gordon Mather Riddick, Jr.
