Derek,
I would like to thank you for your very informative reply, this is my first post on this site and all the replies have been so helpful.
I was aware of "The Fruit of Experience" I have read somewhere that the piece of mutton on Sunday would have to last until Thursday.
I think the Etwall family seems the most likely.
According to Richard's grave his father John lived in Wooburn, Buckinghamshire, so I am presuming he died there.
From Richard's will I already have the following children.
John 1736 - 1836
Richard 1743 - 1815
William
Sarah
Hannah
Sarah married Joannes Kerschner in London in 1779, I do wonder if you had to have "Crossley" in your name to inherit, on this side of the family 1st cousin married 1st cousin, but they never had children, so their share went laterally, one Ernest Augustas Kerschner, changed his name by deed to Ernest Crossley and then married his cousin Sarah Crossley Brock (nee Kerschner) so she became Sarah Crossley Crossley!
I know William had two daughters Elizabeth and Catherine from the will but I have a feeling that William married Bridget in Hollington and they had six children,
John Crossley 1776 - 1845 in Chalfont St Giles his will is all based on bequests from Richard,
Elizabeth married Joseph Beeston
Mary Crossley married William Irwin
Catherine Crossley married Thomas Garratt
Again, there were marriages by 1st cousins on this side of the family.
John Crossley born 1736, is mentioned in a book "History and Antiquities of Uttoxeter" regarding the rebellion of 1745 "The late Mr. Crossley, of the Old Turnpike Uttoxeter who died in 1835 at the age of 100 years and eight months, was then a youth at Brailsford, of about 11 years, and he, with a horse and cart, were pressed into the service of the Pretender as he returned"
John's grave is one of the few still standing in Uttoxeter churchyard.
John Crossley married twice, Mary Newman who died in 1812, I am not sure if there were any children from that marriage, he then married Sarah who was born in 1786, their 1st son was John Crossley born 1814, and this is another nephew who inherited from Richard. John married Louisa Roobotom and accumulated even more wealth with property, he died in 1879 with no issue, his wife died in 1885 and probate was granted to Walter Charles Towers Mynors (nephew) I have not fitted him into the tree yet. The bulk of John's estate again followed the will of Richard, and the bulk went to another nephew, the son of John's brother William who was born 1816 Heath Top, Derbyshire, there were then approximately 30 nephews and nieces who received £100 each, not bad in 1879, one of them being my Great grand father Edgar Crossley who went on to manage the first Boots the chemists in Derby. Edgar's Grandson Martin du Sautoy a former teacher at Herbert Strutts, a deputy mayor and town councillor has recently died and most of my information has come from going through all the papers I have been left.
So I bring this story to the present day, and I really hope I have not bored anyone who reads it. My quest will continue.
with many thanks
Steve
