Emily died July 1881 in Howell, Michigan, per the Michigan death records. Confirmed by my late grandmother. Emily did not return to England. Husband William Ranger, a widower, later remarried.
Are you descended from this Ranger family? I descend from William & Emily's daughter - Maud Ranger, who married Robert L. Pappy, and lived in Daytona and Jacksonville, FL, where she is buried.

Sincerely,
Greg C. White
