Benjamin Franklin's son, William Franklin (b. 1730) was the father of William Temple Franklin, called Temple (b. 1762). There is no Jr. or Sr. William Temple Franklin had a son, Theophile (b. 1785/1790), with Blanche Caillot, and a daughter, Ellen (b. 1798), with Ellen Johnson D'Evelin, sister of his father's second wife, Mary D'Evelin. Ellen Franklin was raised by her grandfather, William Franklin. According to Willard Randall, author of A Little Revenge: Benjamin Franklin & His Son, (Boston, Little, Brown and Company, 1984, p. 494), "Temple abandoned his mistress, William's sister-in-law, and his illegitimate daughter Ellen and went off to Paris. There he sired another daughter by the wife of the British ambassador." This child apparently died in infancy, as did Theophile. Ellen Franklin, however, reached adulthood and married Capel Hanbury. They had a daughter Maria Hanbury, said to be living in Nice, France in the 1870s, who died unmarried, thus ending the line for William Franklin. If anyone has information about Maria or Capel Hanbury, please let me know. Thank you--Elly Fitzig, Manager, Descendants Project, The Friends of Franklin, Inc.
