Hello Clincher,
Please accept my apologies for this late reply to your posting on Dec 1st, I have only just discovered it, I weas playing around on the site and happened to click on to where you can access replies for any postings, I had thought I saw any replies when I visited the board in the usual way, but had missed out on these ones, so sorry about this.
The information you have given re Ovington and the baptisms for Jervis, which I do know was the early spelling of the name, is of great interest to my son and myself, he had searched some years ago in the record office at Chelmsford for baptisms, but had not found the ones you have given.
Any baptisms are early, because later on Job became converted to the Essex religious group of the "Peculiar People" (now known as Evangelists) and they did not practise infant baptism, so we could use only the census to trace the family, which of course meant that quite a number could be missed out, possibly having born & died within the 10 years between the census information.
Any other details you may have come upon for them in Ovington, would certainly be very much appreciated.
Once again, thank you for your help and interest, and apologies for my lateness in responding.
