I am trying to track down the parents and family of Sibyl Exley, who was born in Apperley Bridge, Bradford, West Yorkshire BD10, England (parish of Guiseley) in about 1816. She married William Winterburn of Beamsley (1817-1879). The earliest record I have of her is the 1851 census when she was a servant at Manningham Hall, aged 35. There is also an Elizabeth Exley aged 42 in the same house, which I think might be her older sister. I can't find her in the 1841 census and I can't find a christening record for her.
