The boy who was born on April 2, 1743, in the recently erected farmhouse at Shadwell, on the bank of the Rivanna, never gave much thought to his lineage in his later life. Yet Virginians of good stock were always proud of their ancestry, and more than once he was told by his mother that the Randolphs could "trace their pedigree far back in England and Scotland." Jefferson's mother and John Marshall's grandmother were descended from William Randolph and Mary Isham, both of the English gentry, and Jane Randolph, issued from the best blood in the Old Dominion, had married when she was nineteen a man without means, whose education had been neglected, but sturdy and industrious and belonging to one of the proudest and most aristocratic lines of old Virginians.
Of his mother, Jefferson has told us very little either in his letters or in his "Autobiography." We may surmise she had the refined, modest, unobtrusive and yet efficient qualities so marked in the Virginia girls of the Colonial days and so often noticed by travelers. Sons are apt to mold their feminine ideal on the memory of their mother, and Jefferson may have been thinking both of her and of his wife when, many years later, he contrasted French frivolity with Virginian virtues:
In America, the society of your husband, the fond cares for the children, the arrangements of the house, the improvements of the grounds, fill every moment with a useful and healthy activity.... The intervals of leisure are filled by the society of real friends, whose affections are not thinned to cobweb, by being spread over a thousand objects. This is the picture, in the light it is presented to my mind.[1]
The fond cares for her children would have been ample to fill all the minutes of Jefferson's mother. Large families were the rule in Virginia; fifteen children were born to Thomas Marshall and Mary Keith, and Jefferson's family was no exception to the rule. Between 1740 and 1755, Jane Randolph gave ten children to Peter Jefferson; Thomas was the third child and the first son.
What information he gave about his father has to be completed from other sources. The tradition in the family was that "the first paternal ancestor came from Wales, and from near the mountain of Snowdon, the highest in Great Britain." Peter Jefferson, landowner, practical surveyor, of gigantic stature and strength, had the sturdy qualities and ambition of the pioneer. He received a colonelcy in the militia, became a member of the House of Burgesses in 1755, and in 1749 had been chosen with Joshua Fry, professor of mathematics in William and Mary College, to continue the boundary line between Virginia and North Carolina. "He was afterwards employed with the same Mr. Fry to make the first map of Virginia which was ever made." Besides his association with Fry, from whom he drew the theoretical knowledge of mathematics in which he was lacking, Peter Jefferson improved himself by much reading, not novels, but the serious and sound books which constituted the ordinary family library in colonial Virginia,--historians, essayists, and most of all Shakespeare. For in Virginia as well as in New England, Shakespeare and the Bible were the two books found in every household, the two richest springs of the modern English language. Religion took up as much of their life as in New England. Prayers were said three and sometimes four times a day, and from his earliest infancy, Jefferson became familiar with the liturgy of the Church of England, and had stamped in his memory the strong old words, vigorous phrases and noble speech of King James' version.
