I cant help with Parish Records but this caught my eye 
Sarah FERNIHOUGH
Christened 13 July 1783, Ipstones, Stafford
Parents, John and Mary
Marriages often occurred in Brides parish. It is a submitted record but has batch no.If you check it out on familysearch the batch has other children and couple of deaths as well for probably earlier generation.
It may be the Sarah Fernihough I am looking for on my wife's side of the family.
She married Solomon Ash in St Edward the Confessor's in Leek (which seems the go-to place for the Ashes over the centuries) on August 15th, 1803.
The marriage immediately afterwards was between a John Fernihough and a Hannah Ash - he is, as far as I can tell, the son of John and Mary Fernihough, baptised in St Leonard's on Mar 9th, 1778; she is the daughter of another Solomon Ash who might be the first Solomon Ash's uncle or father (the relevant pages of the St Edward the Confessor's parish records are too faded to make anything out for Solomon Ash's birth).
Both marriages are witness by Wm Beresford and W Hilliard.
We have Sarah Ash already widowed and living with her children in the 1841 census (and Phoebe Fallows nee Ash, who is either her husband Solomon's half-sister or first cousin):

https://familysearch.org/ark:/61903/1:1:QKKM-VCZGShe died in Ipstones in 1859 aged 79 and is buried there - her fine gravestone (carved by the grandson) stands in the far corner of the older part of St Leonard's churchyard:

So it is a good fit for her being that Sarah Fernihough. However, the St Leonard's parish records are painful to go through and another one born a couple of years earlier might have slipped through the net.
Oh and the original query better late than never:
does anyone have access to the parish registers of st.leonards ipstones.i am interested in the following marriage.
SAMUEL EGERTON to SARAH FERNYHOUGH
JULY 9 1805.
thank you.
It says the following:
Samuel Egerton of Barlaston parish aged 21 & upwards bachelor and Sarah Fernyhough of this parish were married by licence (granted by Wm Fernyhough clerk & [something I can't read]) on this ninth day of July 1805 by me William Carlisle curate. They both sign their names (she signs it Fern
ihough) and the witnesses are Hannah Fernihough and Wm Bridgwood.
It could easily be the same Hannah Fernihough (Ash) signature - she certainly doesn't seem used to such a long surname as she runs out of room and has to put the "gh" tucked underneath. Interestingly, both Sarah Fernihoughs' signatures are rather shaky and poor quality, while Solomon Ash's and John Fernihough's are stronger and more confident (the Ashes seemed capable of reading and writing as far back as we can find records).
