They all seemed to marry their neighbors in those days, for Sue, another daughter of Dr. Tyler's married Granville Hyde across the street.
The Hyde's house was next door to the Cassin's on the south. One can see that it is quite old, and it seems that it was built about 1798 by Charles Beatty, one of our old friends of the early days of George Town. He ran one of the ferries across the river to the Virginia shore. About 1806 he had sold the house to Nicholas Hedges; then it went to James Belt in 1822, and to Joshua Stuart in 1832. Later, it was bought by Mr. Thomas Hyde, one of the early merchants of Georgetown. His son, Anthony continued to live there and was for many years secretary to Mr. W. W. Corcoran. Anthony Hyde was very musical and was part of the orchestra which furnished the music in Christ Church before it had an organ. Here grew up Mr. Thomas Hyde, who was very prominent in Riggs Bank and an early president of the Chevy Chase Club. He was a very distinguished looking man to the day of his death.
On the northeast corner of Washington (30th) and Gay (N) Streets is where tradition says Ninian Beall built his hunting cabin when he landed here. That could be borne out by the fact that a very fine spring of water was on that property. Many, many years later the family of Judge Dunlop at 3014 N Street used to send for pitchers of water from that spring, as they had an inherited right to do so.
The long, red building there, now the Colonial Apartments, is still spoken of as The Seminary. It was there that Miss Lydia English conducted her fashionable school for young ladies for many years before the Civil War. This was the school to which Andrew Johnson, while senator from Tennessee, sent his daughter. Years after, when he was being criticized for his defense of Roman Catholics, his enemies brought against him the fact that he had sent his daughter to a "convent" in Georgetown. They had confused the Visitation Convent with Miss English's Seminary. It is said that the roster of the patrons of this school in those ante-bellum days included the names of the most famous men in the country.

Among those names was that of Senator Thomas Hart Benton of Missouri, nicknamed "Old Bullion," on account of his opposition to paper currency. He was one of the supporters of President Andrew Jackson in his war on the United States Bank. One of the pupils at the Seminary was his daughter, Jessie Benton, who afterwards became the wife of General C. Fremont, known as "The Pathfinder of the Rocky Mountains."
Miss English had large means of her own, which enabled her to keep her school going in spite of "ups and downs." But, when in need of advice, she would always turn to her near neighbor, James Cassin.
At one time she had nine teachers besides herself. In 1835 she had 130 pupils. It is said she was a stern headmistress, but she stood for all that was fine, and meant a great deal to Georgetown.
