Thank you very much everyone who has responded so far, Rolnora`s baptism information would appear to be spot on in my opinion, as there are a couple of things that tie it in with the information I already have.
1 The father`s name is Richard as given on the marriage details to Emma Roberts
2 The fathers occupation is labourer as in Johnathan`s marriage details
2 The baptism in Woodchurch is in the area of Birkinhead, Emma his wife was born in Thurstaston
I presume the first Johnathan Smith (found by Rolnora) that was baptised however died at some point and hence Richard & Ann called there next son Johnathan also.
I have looked for the surviving Johnathan in the 1851 census and found him living at what looks like No2 Halls Court Oxton Cheshire with
Richard Smith 34
Ann Smith 37
James Smith 12
William Smith 8
George Smith 6
Richard Smith 4
I have also found him in the 1861 census in Oxton again with
Richard Smith 44
Ann Smith 46
Richard Smith 15
Thomas Smith 7
It is interesting that he has a sibling called William as Johnathan has a grandson called William born around 1896 in Oldham to his daughter Emma Smith, so it is starting me to think that this is "our" Johnathan Smith
However I can`t find a plausible death date for him, as mentioned in my post of 2016 by 1871 his wife(Emma ne Roberts) is living in Bury, Lancashire with her daughter but not with him.
I do not know where he has gone.
Emma his wife eventually hooks up with a Michael Fanning and she is with him in the 1881 Census both of them moving to Oldham and Michael dieing there.
However I have never found a marriage record for these two(Michael Fanning & Emma) , it makes me wonder if Johnathan just deserted Emma, or Emma & Michael just didn`t marry for what ever reason even though their children used his name in subsequent census.
