Elizabeth Dudley was probably a daughter of John Dudley and Elizabeth Whorwood. However, in 1637 and 1641 she wrote letters to Ferdinando Fairfax, 2nd Lord Fairfax of Cameron about his son Charles Fairfax, and addressed Fairfax as "father" and affectionately signed herself "daughter". Theodosia Harington was her aunt, and the mother of Anne Dudley who was placed in the household of Princess Elizabeth. Elizabeth Dudley was probably chosen to join the household through this family connection. She appears in a list of April 1613 of those going toHeidelberg. In 1622 Elizabeth Dudley married Johann Kasimir, Count of Löwenstein-Scharffeneck, but he died later in the year. In her letters the queen referred to the countess as her "Wise Widow", "Dutch Bess Dudly", "my reverend Countess", or "Dulcinea". Löwenstein's correspondents in 1622 included the Count de la Tour. In 1625 a tour of North Holland by Elizabeth of Bohemia and Amalia van Solms was described in a letter, probably written by Margaret Croft. The countess was at the centre of several comic incidents. In 1637 Croft told a story in London that Dudley had boxed the ears of Elisabeth of the Palatinate in front of twenty people in the garden of the Prince of Orange. Another comic piece in French features Löwenstein; "The faithful and true record of the acts, progresses, and skill of the Countess of Levenstein, as ambassador of the Queen, during her stay at Breda", she was not an accredited ambassador, and the jokes revolve around her food, facial expressions, and occasional use of German phrases. The Countess travelled to England, apparently to raise support and funds for the Palatinate cause. John Penington noted her as his passenger in the Convertine to the Brill Road with Lord and Lady Strange and her brother, the "Count Delavoall", Frédéric de La Trémoille, Count de Laval, in April 1631. In 1639, after staying in Bertie House in Lincoln's Inn Fields, she returned to The Hague in Pennington's ship with Lady Strange, "a good ship, excellent company, a fair wind, for one that wished herself at the Hague". She corresponded with Constantijn Huygens, joking that he was a "witch", mentioning that Lady Stafford was sending a theorbo, and writing;
"In England there is nothing spoken of but the troublesome war which is like to be with Scotland, and without the great mercie of God it will be the ruin of both the kingdoms: those officers his Highness hath lent the King, which every body says his Majesty takes very kindly, will find the difference in the order of the wars in Flanders and the disorder there"
She continued the "witch" theme in their correspondence, signing off, "I am confident your witchcraft cannot make me esteem more than I do your merits", while Huygens played along in French and became "le sorcier". In another letter of 1639 she reminded Huygens of his old affection for Lady Stafford, in London 17 years earlier. An English soldier, Captain and then Colonel of the Anglo-Dutch Brigade, Sir Ferdinando Knightly from Fawsley appears in Dudley's letters of 1640, and had some kind of relationship with her. In 1644 Huygens wrote to Knightly that his recent promotion to Colonel at "Bergen op Zoom" would soften the widowed countess's "white marble into warm wax". She wrote from the Hague to Lady Elizabeth Broughton, a former lady in waiting, and her husband Sir Edward Broughton at Marchwiel Hall near Wrexham, with news of their son, and assured them that Elizabeth of Bohemia "will never doubt the affection of the worthy Welsh men for she knows they are honest and Brave Men". When Elizabeth of Bohemia died in London in 1662, she arranged the queen's possessions for probate and secured some jewels and goods to cover money she had lent over the years. She returned to the Hague where Marmaduke Rawdon an antiquary from York saw her and "her nieces", acquaintances of his party.
