Darius and his twin brother Cyrus were the sons of the Reverend Sylvanus and Eunice Hale Waite Cobb.

Eunice Hale (Waite) Cobb, the mother of Darius and Cyrus, founded the first women's club in America, the Ladies Physiological Institute, which promoted health and fitness.

Of those children, Frederick resided in Newton Upper Falls, Massachusetts, and was shipping agent for the Pettee Machine Works.

Ernest purchased the old Cunningham estate on Richardson Road in 1918 from which he and his wife, Bertha, successfully operated the Arlo Publishing Company which featured children's books.

[3] Eventually, Darius moved his family to Newton Upper Falls in the early 1880s, where he resided for the rest of his life.

[4] Cyrus Cobb's two best-known public sculptures are the Soldier's Monument (co-created with brother Darius) on the Cambridge Common and the full-length portrayal of Paul Revere at Boston.

But when Darius Cobb set out in the 1870s to make a still-life lithograph of Civil War artifacts, he was missing one important element - a tin cup.

Later in life the Cobb brothers worked together on a series of paintings illustrating French history for Boston's Tuileries Apartment Hotel.

His research in preparation for the volumes led to the discovery of the long-lost BRADFORD MANUSCRIPT "of Plimouth Plantation" which was eventually returned from its place of deposit in England and is now preserved in the State House at Boston.

The portrait of Reverend John Stetson Barry by Darius Cobb is in the private collection of Mrs. Barbara C. Gray of Gilmanton, NH.

In 1890, Cobb painted a portrait of Civil War General Benjamin Butler at the State House in Concord, New Hampshire.

In 1897, assisted by his brother Cyrus, he decorated the walls of the banquet hall of the Tuileries, Boston, with panels illustrative of French history.

According to The Town Crier (Newton Upper Falls, Massachusetts) for May 5, 1911, 10,000 postal cards printed with Cobb's painting of the Last Comrade's Final Tribute were circulated throughout the United States.

Still, his legacy lives on, as many of his finest pieces are included among many important collections, with specific works on display at the Peabody Essex Museum in Salem, Massachusetts, the Butler Institute of American Art in Youngstown, Ohio, and the State House in Concord, New Hampshire.

According to The Autobiography of William Sanders Scarborough, Cobb's paintings also hung in art galleries in England and France.
