Hello,
I’ve only just seen this topic.
As Sloe Gin said, the Berks Baptisms Index is done by volunteers of Berks FHS. And I did Newbury, St Nicholas 1813 to 1828 back in May 2017 (as well as a working book that includes dates of birth and actual streets rather than just “Newbury”). It would have been checked by someone else, and was published on disc in the 3rd Edition which came out in April this year. This data will appear on Findmypast, but I’m not sure of the timescale.
I think the Society is aiming to do a disc soon of all the St Nicholas registers, which will be a must for us Newburians.
I think you have to be a bit careful here, as there are a number of Willis families in Newbury at this time; and quite a few tailors!
There is a Charles in 1817, son of Samuel (bricklayer) and Lucy, but there is also a Charles in 1819, son of Benjamin (tailor) and Rebecca.
Samuel and Lucy had a George in 1820, but there is also a George in 1825, son of Samuel (tailor) and Charlotte.
The only James I can see in this batch was in 1817, son of Isaac (shoemaker) and Jane.
What led you to Charles born 1817, and Samuel and Lucy as his possible parents?
