Thanks Garstonite and Genhunter. I think this is search is going to take some time - I will look up the Bebington marriage next week at the archives and see if this turns up anything. I am still hunting for either the deaths or marriages of the following of the girls
Mary baptised:1812
Ann baptised: 1815
Elizabeth baptised: 1818 and Sarah b: 1826
The other curiosity I have is the baptisms of the three children all recorded on the same date in 1826 namely Fanny, Sarah and John. I realise that families often had them baptised in a 'job lot' so to speak, but this is quite a gap from 1818 so they may have been a few years old when baptised.
I know from Fanny's marriage certificate of 1841 that she was 19 so she would have been born circa 1822.
Is there an elder brother somewhere named Joseph who marries an Elizabeth - this would make the younger children (on the 1841) cousins of Mary, Samuel and Robert. This brings me back to the marriage that I have for Joseph and Mary Okell which I have as 1807. I am begining to wonder if I have the wrong marriage and that there is an earlier one for a Joseph and Mary which would have produced more offspring than those I have of Mary, Samuel and Robert and allowed for an elder brother named Joseph?

?
Anymore ideas Rootchatters please?
