Question: Who was the wife of FitzWilliam's brother-in-law? Passage 1:He was born in Melbourne to factory storeman Charles Edward Feltham and Annie Clarke, and was orphaned by the age of fourteen. He attended Melbourne High School and the University of Melbourne, where he received a Master of Law. He became a solicitor in Shepparton. On 16 November 1929 he married Sylvia Josephine Box, with whom he had two children. During World War II he served first in the AIF and then in the Royal Australian Air Force, in which he rose to the rank of wing commander and was attached to the staff of General Douglas MacArthur. He was appointed a Member of the Order of the British Empire in 1943. After the war he returned to his law practice, and also farmed at Wyuna. In 1955 he was elected to the Victorian Legislative Council as a Country Party member for Northern Province. In 1965 he left the Country Party after falling out with leader George Moss over the presidency of the Council, and became an independent. He was defeated in 1967. Feltham died in 1986.

Hamburger received his B.A., M.A and Ph.D from Yale and has previously held professorships at Oberlin College and the University of Toronto. Elected a Fellow of the Medieval Academy in 2001, he has won numerous awards for his publications, among them: the Charles Rufus Morey Prize of the College Art Association (1999), the Roland H.

In 2009 Hamburger was elected a member of the American Academy of Arts and Sciences and in 2010, of the American Philosophical Society. In 2015 he was awarded an Anneliese Maier Research Award by the Alexander von Humboldt Foundation.
 Passage 3:He was both a Catholic and a royalist, and enjoyed the confidence of Queen Henrietta Maria, who recommended him to Charles I as "a man deserving of every encouragement." In 1645 he tried to get the Confederation of Kilkenny to support King Charles I in the English Civil War on the grounds that their demands for full civic rights to be restored to Roman Catholics would be met. He fought with the Confederates against the Parliamentarians in 1645–6, and led a successful assault on Roscommon Castle in 1646. In 1649 he was imprisoned in London but soon released. After some time in France he was allowed to return to England through the pleas of his brother-in-law John Holles, 2nd Earl of Clare. He is said to have been one of the few Irishmen whom Oliver Cromwell admired, and was also on good terms with Oliver's son Henry Cromwell, although Henry refused his request to be allowed to recover possession of his principal residence, Merrion Castle. During the Commonwealth he seems to have played a careful double game- his second marriage into the Holles family put him in the Parliamentarian camp, but he was also suspected of working for the Restoration of Charles II.
