Benjamin Franklin

Our Cousin, the Polymath — 1706–1790

The man on the $100 bill is family.

The Connection

Benjamin Franklin’s mother was Abiah Folger (1667–1752), daughter of Peter Folger (1617–1690) of Nantucket — missionary, interpreter to the Wampanoag, poet, and one of the founding settlers of the island.

Peter Folger is our documented ancestor through the Nantucket Folger line.

The Love of Books

Franklin taught himself to write by borrowing books he couldn’t afford, reading them overnight, and returning them before dawn. At twenty-five he founded America’s first lending library. He believed knowledge should be accessible to everyone, not locked behind wealth.

His autobiography — still in print after 230+ years — remains one of the most widely read American books ever written.

Lucretia Mott — The Next Generation

Lucretia Coffin Mott (1793–1880), born on Nantucket. Father: Captain Thomas Coffin, whale-fisherman, descendant of the original purchasers of Nantucket — our Coffin line. Mother: Anna Folger — our Folger line. Lucretia was Benjamin Franklin’s cousin — and ours.

She became the greatest American woman reformer of the nineteenth century: Quaker minister, abolitionist, co-organizer of the Seneca Falls Convention (1848), co-author of the Declaration of Sentiments, president of the American Equal Rights Association. Her home was a stop on the Underground Railroad. She co-founded Swarthmore College and the Female Medical College of Pennsylvania.

The Folger Thread

Peter Folger(Nantucket founder) → Abiah Folger → Benjamin Franklin.

Peter Folger → (through another line) → Anna Folger → Lucretia Coffin Mott.

And Thomas Coffin (Tristram Coffin’s descendant) → Lucretia Coffin Mott.
