we were excited when Lancashire Online Parish Clerks' website posted the name 'Jerens' but it became less likely when we tried to find a jerens johnson in any other searches. Currently this has stopped our progress as all we know of this man is that he was a shopkeeper, potentially in Liverpool (his son stephen Johnson was born in Liverpool in1807) .
The LOPC website has indeed got as its source the micro film which is identical to our paper copy. We have been in contact with the church which is not far from where we live but communication with them has not been great.
We will keep on researching as this takes us into the 1700's all but the last two generations living in tyldesley.
