The direct senior line of the de la POMEROY barons came to an abrupt, childless end in 1416 upon the death of Sir John de la POMEROY. This sudden demographic vacuum triggered a massive, multi-year inheritance war across the high courts of London, as rival cousins, predatory land speculators, and regional syndicates attempted to manufacture fraudulent deeds and falsify genealogical records to seize the castle and its surrounding manors. The man who successfully recovered the family assets was Edward de la POMEROY, but his victory in the Westminster Court of Common Pleas was entirely financed and legally anchored by his marriage to Margaret Bevile, the sole heiress of John Bevile of Woolston, Cornwall.

Margaret Bevile inherited an immense fortune in her own right, including extensive mineral-rich lands, lucrative tin mines, and high-yielding coastal manors across Cornwall. When Edward faced ruinous legal fees fighting the internal family fraud ring, Margaret liquidated a portion of her Cornish properties to bankroll the high-court litigation. After proving the forgery of the rival deeds using historical seals and strict fee tail laws, the couple took physical possession of Berry POMEROY Castle. Margaret then used the remainder of her independent Bevile fortune to fund a massive architectural transformation of the fortress, tearing down the dark, defensive medieval walls to construct a late-medieval palace wing complete with expansive glass windows, grand halls, and decorative carvings, permanently shifting the property from a military outpost into an elite Renaissance seat.
