Hi Jan,
Just my opinion and others may not agree

but think the 1817 James WildGOOSE christening is the right one to James and Mary.
Remember ages were often rounded on Census details.
I also think the James Wildgoose, born 1785 , Bulwell, could be his Father. He married Mary GENT, 26 Dec. 1806, Bullwell.
There could also be children born to this couple who had left home by 1841 census.
From 1841 census, Ellen aged 11 seems to be baptised as Wildgoose + Elijah and Charles. Their ages are a few years out on census also.
