Thanks Bob 

  I saw the Dewsbury one too and have tried to follow him, but got nowhere 

  I wonder if he is just a red herring.  There are a couple of marriages in Dewsbury after 1851, one I have ruled out for 1855 because this Jeremiah is marrying 2nd wife Martha and he was born c 1789, a blanket maker...
the other to Ellen Shore in 1865, I haven't been able to track this couple on later census yet 

The Davidson's were baptised at St Michael, Workington, to James and Mary. However their first sone was baptised at Carlisle, and father James puts place of birth as Carlisle on census.  I am pretty sure I have the right marriage of James Davidson to mary Nixon at Carlisle, but I was hoping that by tying up who Jermiah/Jeremiah was I could confirm this.  I was thinking that he was maybe connected through mum Mary, e.g if a sister marrried a Williamson., but I seem to be go around in circles 

The only other maybe I have for Jermiah is a Jermiah Wilkinson on the 1841 census... maybe his name is written wrong on the 1851
