Hi Jinks, (sorry couldn't resist

)
I've not come across a Pye in my tree (yet), but these Simpsons are a bit distant, so I've not fully explored them.
They come in when a great (x3) great-aunt, Isabella Marsden (1794-1871) marries a John Simpson (1795? - 1845) in Slaidburn on 13 Nov 1819. (I've just posted a bit more on these Marsdens and a Winder marriage
here on this thread.)
I've not found the couple on the 1841 census (probably just not looked hard enough), but the widowed Isabella Simpson is on the 1851 and 1861 censuses as a farmer of 94 acres at Lower Moorside in Over Wyresdale, before appearing on the 1871 census at Sharoe Green, Preston, where she died 28 Nov 1871
I think this is John and Isabella Simpson's gravestone in Over Wyresdale churchyard:
IN AFFECTIONATE REMEMBRANCE OF
JOHN SIMPSON
WHO DEPARTED THIS LIFE SEPR 27TH 1845
AGED 50 YEARS
ALSO OF ISABELLA, WIFE OF THE ABOVE,
WHO DEPARTED T[HIS LI]FE NOVR 26TH 1871
AGE[D ... YE]ARS
Very irritating blob of lichen in just the wrong place!
