I have read that Millom Castle in the 12th century was designated to
the family of Huddleston, Hudleston or Huddlestone depending on who recorded it. I have reason to believe that Rudolph Hudson b. abt 1465 (the name he was buried with) may have been born with the surname Herdson a derivative to avoid personal taxes. Rudolph apparently was a founder of Russian Trading that later became Muscovy Trading. After moving to the London vicinity (Tamworth Castle) the name Hudson was used. Research is vague and the library of Orkney has been suggested though their fees appear to be very expensive. Any other suggestions are appreciated!
from Encyclopedia Britannica
Muscovy Company, also called Russia Company, body of English merchants trading with Russia. The company was formed in 1555 by the navigator and explorer Sebastian Cabot and various London merchants and was granted a monopoly of Anglo-Russian trade. It was the first English joint-stock company in which the capital remained regularly in use instead of being repaid after every voyage. In 1553 Sir Hugh Willoughby and Richard Chancellor had sailed to seek out a Northeast Passage to China and the East Indies (Indonesian archipelago). Willoughby’s ship was lost, but Chancellor reached Arkhangelsk (Archangel) on the White Sea and established trade links with Moscow.
