Hi Irene,
Do you want the good news

or the not so good news

or the bad news

Start with the bad news Adderley and Norton are not there - ONLY Whitchurch - nowhere else - except for the censuses
The not so good news the records are typed from 1745 -1812 and then on fiche from 1813-1892 - so not much extra information on the typed copies - only witnesses.
Right - now the good news - I found the rest and some more Chester/s while I looked at the baptisms - hope 1758 doesn't throw you to much!!
