Phipps interests held the largest numbers of voting stocks of the International Paper & Power Co. in 1930, also the same interests held the largest number of shares of common stock of the New England Co. before it was reorganized into the New England Power Association in 1926.....¶ The International Paper & Power Co. controlled the International Hydro-Electric System by ownership directly or indirectly of more than 95 percent of the voting stocks. The International Hydro-Electric System controlled 87.55 percent of the common stock of the New England Power Association, thus controlling that company."
During the Second World War Mrs [Margaret Grace] Phipps invited 30 British children to live with them at the mansion. Jay survived his wife by one year, dying in 1958 and having contemplated the future of the estate in the rose garden, their daughter, Peggy Boegner (1906-2006), decided to open it to the public and with her siblings established The J.S. Phipps Foundation in order to preserve the estate for prosperity.
Since 1936, Mr. Phipps had published and edited The Fauquier Democrat, a weekly newspaper issued here in Fauquier County.
