Hi Peter, and many thanks for the prompt reply. William was born on the 21st march and christened on April 30th, 1815 in Leighton Green according to the Bishops records for Coppenhall.
The 1841 census records his age as 25 which suggests he was born even as late as 1816. The 1851 census records him as being 36 ,thus making 1815 the birthyear.
His son Peter, my Great grandfather, registered his death as 66 yrs, thus my problem.
His marriage was witnessed by a Charles Ashley and John Briscall and there apppears to be no lead there!
Perhaps I should try and access his parentage through his siblings?
I must also review the 1841 census details again to see if I can make the connection there as you suggest? Should I be looking for a 'Brockley' living as a head of household in the same area, aged about 50yrs, as a possible lead as I really do not have strong information on possible Christian names other than William, Samuel, Thomas, John and Joseph as regular family names as a guide? Many thanks again, Ter
