Hi,
My reasonably certain line starts with the marriage of William Cecil to Elizabeth Thomas in Manchester 1795.
He died age 89 in Mar 1850, as William Saycell, giving his birth at 1860ish.
The 1841 census has him, as Saysell, age 76 not born in Lancsahire.
There are almost no earlier records of Cecil/Saycells in Lancashire or nearby counties, and he moved all over the country before settling back in Manchester, so he had to move in there from somewhere else.
I have checked all the records I can find for other William around that time and can find plausible marriages or burials for them all, except for William Cecil baptised 1759, son of Lenard at Cawood.
I have followed the probable line back from there through Leonard 1720 s John, John 1679 s John at Clapham, to John Cicill 1638 Aughton.
This John looks to be a replacement for John 1632 - I must have picked that record out by mistake in my previous message
There is also a tenous connection to Yorkshire with an unexplained family.
In 1881 one of William's sons, Joseph is in Manchester and with him is a Samuel Saycell age 25 nephew, wife Mary and children Samuel, Elizabeth and John.
They are all described as born Manchester.
I've been unable to find anything else, anywhere, about this family.
The only "clue" is that the name Samuel doesn't figure at all in the rest of the Manchester Saycell/Cecil families, but it does crop up in the Sheffield Cecils.
