Thanks for your replies. I don't think Jane and Sarah are one and the same person. There was more than one Stephen Outing around at the time. I do have access to SEAX and have gathered lots of info. in Mountnessing and Buttsbury. It was only the other day that I realised there were a nest of Outings in Blackmore and the Stephen who was buried in Mountnessing appeared to be the one baptised in Blackmore. As he's a direct ancestor, I'm keen to find his parents marriage to help me slot everybody into place!
By the way, the spelling of the name varies a great deal (Outing, Outting, Oughting, Owting) and finally settled on Outten.
