The care of Jack Custis was a worry to Washington in quite another way. As a lad, Custis signed his letters to him as “your most affectionate and dutiful son,” “yet I conceive,” Washington wrote, “there is much greater circumspection to be observed by a guardian than a natural parent.” Soon after assuming charge of the boy, a tutor was secured, who lived at Mount Vernon, but the boy showed little inclination to study, and when fourteen, Washington wrote that “his mind [is] … more turned … to Dogs, Horses and Guns, indeed upon Dress and equipage.” “Having his well being much at heart,” Washington wished to make him “fit for more useful purposes than [a] horse racer,” and so Jack was placed with a clergyman, who agreed to instruct him, and with him he lived, except for some home visits, for three years. Unfortunately, the lad, like the true Virginian planter of his day, had no taste for study, and had “a propensity for the [fair] sex.” After two or three flirtations, he engaged himself, without the knowledge of his mother or guardian, to Nellie Calvert, a match to which no objection could be made, except that, owing to his “youth and fickleness,” “he may either change and therefore injure the young lady; or that it may precipitate him into a marriage before, I am certain, he has ever bestowed a serious thought of the consequences; by which means his education is interrupted.” To avoid this danger, Washington took his ward to New York and entered him in King’s College, but the death of Patsy Custis put a termination to study, for Mrs. Washington could not bear to have the lad at such a distance, and Washington “did not care, as he is the last of the family, to push my opposition too far.” Accordingly, Jack returned to Virginia and promptly married.
