Question: Who was the father of the 6th Baron from the family of Cumbria, England?

<P0-S0> Sizergh Castle and Garden is a stately home and garden at Helsington in the English county of Cumbria, about 4 mi south of Kendal. <P0-S1>  The castle, a grade I listed building, is in the care of the National Trust along with its garden and estate. <P0-S2>  It is the home of the Hornyold-Strickland family. <SEP> <P1-S0> Baron Rolle was a title created twice in the Peerage of Great Britain for members of the Rolle family, related as uncle and nephew. <P1-S1>  This family was established at the manor of Stevenstone in Devon in the 16th century. <P1-S2>  In the 17th century they acquired additional estates in Devon including Bicton when Sir Henry Rolle (d.1617) married Anne Denys, a co-heiress of Bicton and Holcombe Burnell. <P1-S3>  In 1748 Henry Rolle, previously Member of Parliament for Devon and Barnstaple, was made Lord Rolle, Baron of Stevenstone, in the County of Devon. <P1-S4>  The title became extinct on his early death in 1750. <P1-S5>  His nephew John Rolle inherited the family estates in 1779 and in 1796 was made Baron Rolle, of Stevenstone in the County of Devon. <P1-S6>  The title became extinct on his death in 1842. <P1-S7>  He bequeathed his estates, then some 55000 acre , to Hon. Mark Trefusis (d.1907), second son of the 19th Baron Clinton, the nephew of his second wife and widow, who was required by the will to adopt the surname and arms of Rolle, which he did by royal licence in 1852. <P1-S8>  In 1907 he too died without male progeny when, in accordance with the entail created by the will of Lord Rolle, the Rolle estates descended to his nephew Charles Trefusis, 21st Baron Clinton (1863–1957) of Heanton Satchville, Huish. <P1-S9>  The Trefusis family had in 1791 inherited the great estates of the Rolle family of Heanton Satchville, Petrockstowe, a junior branch of the Rolles of Stevenstone. <P1-S10>  This was due to the eventual heir of Margaret Rolle, "suo jure" 15th Baroness Clinton (1709-1781) having been her cousin Robert George William Trefusis (1764–1797), lord of the manor of Trefusis in Cornwall, who in 1794 successfully claimed the title 17th Baron Clinton. <P1-S11>  Trefusis and Margaret Rolle were both descended from the marriage of Robert Rolle (c.1622-1660) of Heanton Satchville, Petrockstowe and Lady Arabella Clinton, the younger daughter of Theophilus Clinton, 4th Earl of Lincoln, 12th Baron Clinton (d.1667). <P1-S12>  The 21st Baron Clinton sold Stevenstone in 1922, and concentrated his remaining still huge Devon estates in two areas, one in mid-Devon comprising the estates of Rolle of Heanton Satchville, Petrockstowe, the other in east Devon comprising the Bicton and East Budleigh estates of Rolle of Stevenstone. <P1-S13>  All the estates are today managed by the Clinton Devon Estates organisation. <SEP> <P2-S0>  In 1909, the 4th Baron Stanley of Alderley acquired a further title when he succeeded his first cousin once removed, the Earl of Sheffield, according to a special remainder and thus inherited the title of 4th Baron Sheffield. <P2-S1>  He was Liberal Member of Parliament for Oldham. <P2-S2>  After his death, the Stanley of Alderley and Eddisbury baronies remained united; most holders have since chosen to be known as "Lord Stanley of Alderley". <P2-S3>  The 3rd Baron Stanley of Alderley had a career in the Diplomatic Service; as he was childless he was succeeded by his younger brother, the 4th Baron. <P2-S4>  On his death the titles passed to his younger brother, who preferred to be known as Lord Sheffield. <P2-S5>  Upon his death in 1850, he was succeeded as 2nd Baron Stanley of Alderley and 8th Baronet of Alderley Hall by his son Edward, who was a prominent Liberal politician and notably served as President of the Board of Trade, Postmaster General and had in 1848 been created Baron Eddisbury, of Winnington in the County Palatine of Chester, in his own right. <P2-S6>  He only held the titles for three months. <P2-S7>  After his death the titles passed to his son, the 5th Baron Stanley of Alderley. <P2-S8>  He was Liberal Member of Parliament for Eddisbury and also served as Governor of Victoria. <P2-S9>  His wife Henrietta was a prominent campaigner for women's education. <P2-S10>  His eldest son, the 6th Baron Stanley of Alderley, sold the family seat of Alderley Hall in 1938. <P2-S11>  It was created in 1839 for the politician and landowner Sir John Stanley, 7th Baronet. <P2-S12> Baron Stanley of Alderley, in the County of Chester, is a title in the Peerage of the United Kingdom. <P2-S13>  s of 2013 the titles are held by the latter's cousin, the 9th Baron Stanley of Alderley, who succeeded his father in that year. <P2-S14>  He was married four times, the second time to Sylvia Ashley. <SEP> <P3-S0> William Strickland, 6th Baron Boynton, esq. (February 18, 1753 – January 8, 1834) was an 18th-century gentleman farmer and writer from Yorkshire, England. <P3-S1>  He was the eldest son of Sir George Strickland of York, England, from the ancient English Strickland family of Sizergh. <P3-S2>  He established his own farm at Welburn in York and, in 1808, succeeded his father as the sixth baron of Boynton.
