In bringing up his family, Mr. Tyler has been fortunate. His daughters, except the youngest, Alice, who is at school, are happily married, and his sons who are grown, Mr. Robert and Mr. John Tyler, are gentlemen of honor, manliness, and intellect; and Tazwell, his youngest son, is a lad of promise. Miss Elizabeth Tyler, who is now Mrs. Waller, and living with her husband in Virginia, was much admired in her bellehood when in the White House. Her unpretending and gentle manners inspired with admiration all who approached her. 'Well,' exclaimed a fashionably ambitious young lady one day to a gentleman who was attending her on a visit to Miss Tyler, 'if I were Miss Tyler, I'd blaze my bellehood out as long as my father was President, and make the most devoted lover in christendom bide my beck in the crowd.' The fair Virginian had no such ambition, and thereby proved herself worthy of the manly heart that has won her. Mr. ROBERT TYLER, the eldest son of the President, is a young man of brilliant genius. As a poet, in high-wrought and vivid imagery, he resembles Shelley, whose likeness he personally resembles; and as an orator, there is not a speaker of his years in our country who has made a greater impression than he made in two extemporaneous efforts before the Irish Association. Bold, eloquent, and manly, he dashes into his subject with his whole soul, while comprehensiveness, energy, and point characterize every thing he says. Certain persons, forgetting the decencies of life, have abused and calumniated Mr. Robert Tyler in the most gross and libellous manner. It is therefore due to him to say, that a kinder son, a more devoted husband and father, or a firmer friend, those who know him have never known. Magnanimous and chivalrous, he throws no veil over either his actions or opinions; and his frank and high bearing wins the regard of all those who come in personal contact with him, however much they may have been before prejudiced against him. The lady of Mr. Robert Tyler does the honors of the White House. She is the grand-daughter of the late Major Fairlie, of New-York, a soldier of the revolution, and a distinguished citizen, who was well known to many of the oldest inhabitants of that city. Her mother was a celebrated belle, whom our present minister to Spain, Washington Irving, remembers vividly as his friend, and one of the most brilliant women of the day; a fair and witty and most worthy lady, who might well have inspired the author of the 'Sketch Book' with those exalted perceptions of female character which glow so brilliantly in his portraits of the sex. Mr. COOPER, the celebrated tragedian, married this lady, and Mrs. Tyler is their eldest daughter. Three years since Miss Cooper married Mr. Robert Tyler. Dickens says when he visited the White House, that Mrs. Tyler 'acted as the lady of the mansion, and a very interesting, graceful, and accomplished lady too.'
