On a farm located near the Patapsco Eiver, within about ten miles of the city of Baltimore, in the State of Maryland, on the 9th day of November, 1731, Benjamin Banneker was born. Various accounts are given of his ancestry. One of his biographers states that "there was not a drop of white blood in his veins," another asserts with positiveness that his parents and grandparents were all native Africans.[146] In still another sketch of Banneker's life, read before the Maryland Historical Society, on May 1, 1845, it is stated that "Banneker's mother was the child of _natives_ of Africa so that to no admixture of the blood of the white man was he indebted for his peculiar and extraordinary abilities."[147] Thomas Jefferson said that Banneker was the "son of a black man born in Africa and a black woman born in the United States."[148] According to Mrs. Tyson's account Banneker's mother and father were Negroes, but his maternal grandmother was a white woman of English birth, who had been legally married to a native African. The antecedent circumstances of this marriage were so unusual as to justify special mention. Mollie Welsh was an English woman of the servant class, employed on a cattle farm in England where a part of her daily duty was the milking of the cows. She was one day charged with having stolen a pail of milk that had, in fact, been kicked over by a cow. The charge seems to have been taken as proved, and in lieu of a severer punishment she was sentenced to be shipped to America. Being unable to pay for her passage she was sold, on her arrival in America, to a tobacco planter on the Patapsco Eiver to serve a term of seven years to pay the cost of her passage from England. At the end of her period of service, this Mollie Welsh, who is described as "a person of exceedingly fair complexion and moderate mental powers," was able to buy a portion of the farm on which she had worked.[149] In 1692, she purchased two African slaves from a ship in the Chesapeake Bay near Annapolis. One of these slaves named Bannaky, subsequently Anglicized as Banneker, was the son of an African king, and was stolen by slave dealers on the coast of Africa.[150] With these two slaves as her assistants, Mollie Welsh industriously cultivated her farm for a number of years with such gratifying success that she felt impelled afterwards to release her two slaves from bondage. The slave Banneker had gained such favor in the eyes of his owner that she married him directly after releasing him from bondage, notwithstanding the fact that his record for sustained industry had not equalled that of his fellow slave, while serving their owner on her farm--a fact that was perhaps due to Banneker's natural inclination to indulge his royal prerogatives. This Banneker is described as "a man of much intelligence and fine temper, with a very agreeable presence, dignified manner and contemplative habits."[151]
