There are very few records for the Seneca woman known as “Queen Aliquippa,” and only one child, a son named Kanaksusy/Canachquasy can be positively connected to her. He is connected by three events. In June, 1754 at Great Meadows (Fort Necessity) Aliquippa presented her son to George Washington, "Queen Alliquippa desir'd her Son (who is really a great Warrior) might be taken into Council, as She was declining and unfit for Business and that he should have an English Name given him" Washington gave Kanaksusy the name of Col. Fairfax and told him it meant "first in council.” {From George Washington to Robert Dinwiddie, 10 June 1754 (archives.gov) Also in 1754 Kanuksusy met with Pennsylvania Governor Morris, who said, “I am informed that your parents presented you to the late William Penn at Newcastle,” a reference to Penn’s farewell in 1701.
There are no contemporaneous records of Aliquippa’s early life. In 1731 Pennsylvania traders referred to “Aliquippa’s town” in western Pennsylvania. Between 1748 and 1754 there are several records of different visitors, all of whom found her in western Pennsylvania, variously near the Forks of the Ohio in the vicinity of the current town of McKee’s Rocks, PA and along the Youghiogheny, Monongahela, Allegheny, and Ohio rivers. None of them mentioned a spouse or children.
After the July, 1754, defeat at Fort Necessity, about 200 Indians including Aliquippa went to the home of Indian Agent George Croghan at Aughwick for safety. Croghan reported in December, that “"Alequeapy, ye old quine, is dead and left several children (Croghan to Morris, Dec. 23, 1754, Pa. Archives, II, 212-13, 218, 219; Public Records Division, Harrisburg) Who these “children” might be is unknown, since Aliquippa was in her seventies at the time of her death. There is no mention of any names or of white spouses.
Wikitree and endless Internet family trees give Aliquippa a daughter named “Summer’s Eve,” born in the 1820’s, who is most often connected with a husband named “Jacob Stoneking” but I cannot find any mention of any daughters or other children by name.
