Antoine Amedee Marie Vincent Manca de Vallombrosa was born on June 14, 1858 in Paris, France.  He acquired the title of Marquis de Mores at the age of 21. He married Medora von Hoffman, an American heiress, on February 15, 1882 in Cannes, France. They had two sons, Louis and Paul, and one daughter, Athenais.

Hearing rumors of opportunities in Dakota Territory, de Mores traveled there and in April 1883 founded the town of Medora.  He established the Northern Pacific Refrigerator Car Company with hopes of revolutionizing the livestock industry. Local opposition to the Marquis' plans lead to the death of Reiley Luffsey, a suspected rustler. The Marquis was indicted for murder and later was freed on a "not guilty” verdict. The business failed in 1886.

De Mores and his family spent the winter of 1886 in New York and returned to France in 1887.  In 1888 the Marquis promoted the building of a railroad in China but due to political opposition the project was never completed. While on an expedition in Northern Africa the Marquis was murdered. He died at the age of 38 in June 1896.
