Hi Jane,
I'm only just starting to look into this myself, so I'm not clear what the story is yet, but I think Francis Chorley got married in Exton, I think that is also where William and Mary baptised their kids, at least.
http://www.wsom.org.uk/Parreg.htmlMy best guess is William (born c1770) and Mary married in Wiveliscombe and baptised there kids:
William Chorley William/Mary Exton Farmer 26 4 1813 born 7.6.1798
Jane Chorley William/Mary Exton Farmer 26 4 1813 born 16.1.1801
Harriot Chorley William/Mary Exton Farmer 26 4 1813 born 31.5.1802
Francis Chorley William/Mary Exton Farmer 26 4 1813 born 12.7.1803
Robert Chorley William/Mary Exton Farmer 26 4 1813 born 28.2.1805
Anne Chorley William/Mary Exton Farmer 26 4 1813 born 26.9.1807
..in Exton. My next best guess is that Francis son of William married Eliza Ward Paramore in 1839, to which we get William Paramore Chorley born 1841. William Paramore begat Robert Thomas Percical Chorley who begat Albert Leonard Lovebond Chorley who is my granddad.
So it seems, if I'm right, I may be related to William and Mary Chorley, so the next question is, who is this William's parents? Maybe William and Joan?
Got to go to work, but I'll keep looking.
I found there is a Chorley's Farm in Wilveliscombe, its beautiful! And its for sale at the moment. If I had the £700,000 I'd buy it!
