Philippe Mius d’Entremont was born in Normandy, France, and came to Acadia with his family in 1651 as a lieutenant-major with Charles de Saint-Étienne de la Tour, who had been named Governor of Acadia by Louis XIII of France first in 1631, and again by Louis XIV in 1651.
The governor in July 1653 awarded him one of the few fiefs to constitute territory in North America, the first in Acadia, and the second in all Canada, the Barony of Pobomcoup. Pobomcoup, meaning in Mi"kmaq "land from which the trees have been removed to fit it for cultivation", extended from Cap-Nègre (Clyde River) to Cap-Fourchu (Yarmouth). He promoted agriculture on his seigneury and brought to his estate several indentured workers and a few families from Portuguese-Royal.
The settlement and d"Entremont"s residence were established at Pubnico, the modern spelling of Pobomcoup.
In 1654, d"Entremont was captured by Major General Robert Sedgwick when he added Acadia to the British dominions after capturing the forts of Saint John, Portuguese Royal, and the settlement of Penobscot. He did not resurface with his family until the colony was restored to France in 1670.
At this time he was created a procureur du roi (King"s attorney) in Acadia by Governor Hector d"Andigné de Grandfontaine, a post he retained until 1687. The barony of Pobomcoup remained in the family until the Expulsion of the Acadians that began in 1755 by the British.
