She bore him two children. The first was a son, Francis Folger Franklin, an unusually bright, handsome boy, the delight of all that knew him. Franklin had many friends, and seems to have been very much attached to his wife, but this child was the one human being whom he loved with extravagance and devotion. Although believing in inoculation as a remedy for the small-pox, he seems to have been unable to bear the thought of protecting in this way his favorite son; at any rate, he neglected to take the precaution, and the boy died of the disease when only four years old. The father mourned for him long and bitterly, and nearly forty years afterwards, when an old man, could not think of him without a sigh. [Illustration: MRS. SARAH BACHE] The other child was a daughter, Sarah, also very handsome, who married Richard Bache and has left numerous descendants. His illegitimate son, William, was brought home when he was a year old and cared for along with his other children; and William’s illegitimate son, Temple Franklin, was the companion and secretary of his grandfather in England and France. The illegitimate daughter was apparently never brought home, and is not referred to in his writings, except in those occasional letters in which he sends her his love. According to the letter already mentioned as in the collection of the Pennsylvania Historical Society, she was married to John Foxcroft, who was deputy colonial postmaster in Philadelphia. It was well that she was kept away from Franklin’s house, for the presence of William appears to have given trouble enough. A household composed of legitimate and illegitimate children is apt to be inharmonious at times, especially when the mother of the legitimate children is the mistress of the house. Franklin’s biographies tell us that Mrs. Franklin tenderly nurtured William. This may be true, and, judging from expressions in her printed letters, she seems to have been friendly enough with him. But from other sources we find that as William grew up she learned to hate him, and this, with some other secrets of the Franklin household, has been described in the diary of Daniel Fisher:
