George Denison died in Hartford, Connecticut Oct. 23, 1694, while there on some special business. He was 76 year old when he died. His wife, Ann Borodell, died Sept. 26, 1712, aged 97 years. They were both remarkable for magnificent personal appearance, and for force of mind and character. She was always called "Lady Ann." They held a foremost place in Stonington, Connecticut. At the time of their marriage, in 1645, she was 30 years old and he 27. He has been described as "the Miles Standish of the settlement," but he was a greater and more brilliant soldier than Miles Standish. He had no equal in any of the colonies, for conducting a war against the Indians, excepting, perhaps, Captain John Mason.

George's brother, General Daniel Denison wrote in 1672: " My Brother George buried his first Wife (Bridget Thompson) in the year 1643, went to England, was a soldier there about a year (he was a Captain in Cromwell’s cavalry during the English Civil War), was at the Battle of York or Marston Moor where he did good service, was afterward taken prisoner, but got free, and having married a second Wife, he returned to New England the year before our Mother died, and not long afterward removed himself to New London, near whereunto at Stonington he now liveth."

The story is that George met his second wife, Ann Borodell, when he was wounded and took shelter in her father's house. He married her in England and returned to Massachusetts about 1645.

On Captain George Denison and Ann's return to Roxbury, Massachusetts, the young couple was royally welcomed. The governor of Massachusetts, John Winthrop, noted in his diary, “the return of the young captain out of the wars in England, has become quite a hero. His bride charmed everyone. She was tall with brown hair and blue eyes, very pretty. But more than that she was so kind and gracious, so true a gentlewoman that the neighbors called her ‘Lady Ann’”.
