There are some baptisms at North Clifton, I realise that it is some 7 miles from Marnham by road, but at one time there was a ferry across the river at Marnham to South Clifton. Marnham was divided into Church Marnham and Ferry Marnham. Now of course it is High and Low Marnham, there only being the one Church.
There are massive gaps in all the records, sometimes due to missing pages, water and damp ingress, infestation, loss of the registers, Civil War, etc etc.
Records can only be transcribed if they are readable and exist.
