That was a quick response!  A short while ago when researching the history of the Chapel your post 'popped up' - there wasn't anything to add to it at the time. However, yesterday I was preparing for a wedding today and took a photo of a marking on one of the stones very high up on the wall. I haven't had a chance to download it to the PC yet but will send once the wedding has finished later this afternoon. If in the meantime you are interested to see where your ancestor was christened and the history of this manor you can google 'Newlands Chapel Charing': there is a Facebook page and wedding website (kentchapelweddings). Your ancestors were definitely here; my research has been mainly ancient history so it would be interesting to know if they were land owners or tenants.
