SERENDIPITY: There is a delightful, circa 1908 photo of little Phyllis Cass Wardrobe on pg. 180 of the Nov-Dec 1989 issue of "The Genealogical Helper" magazine. This adorable child was the daughter of Josie Ellen Wood Wardrobe and George Ernest Wardrobe of Somerville (Middlesex Co.) Massachusetts.
Sandra M. Clunes, Derwood, MD, who shared the photo of her mother said that as of 1989, Phyllis Cass Wardrobe Marsh was alive and well in Venice, FL.. Please reference that issue for further details.
Hopefully, this "snippet" will provide just the right clue to a researcher.
