In 1758, during the French & Indian War, a party of French soldiers and Shawnee took Mary Jemison from her home 3 miles north of here. Although most of her family and neighbors were killed, Mary was adopted by two Seneca women. Jemison lived with the tribe and in 1762 traveled to their tribal home on the Genesee River. She was known as "the White Woman of the Genesee." At war's end, she was offered her freedom but chose to stay with the tribe.

Maps this old were drawn largely by eye, so places on them can sit miles from where they really are. The pin is ours and marks the marker's location today.

Example

For example, one family's tree showed the Articles of Confederation marker in Pennsylvania standing under a mile from where William Gabby lived in the 1760s.

What that marker records spans 1777 to 1789, overlapping William Gabby's years there.
