Now thats making more sense. Age wise if she was Elizabeth Holms William would have been only 15 when they married which I dont think would have worked.
William Morrell baptised 10th Nov 1805 at Ecclesfield
born 10th October 1805. Fathers name John.
There are other Morrells baptised Ecclesfield.
S&DFHS have a CD and I did find them on Family Search (free)
Not 100% sure about Ancestry & FindMayPast.
Question do the Libraries in Sheffield still give free access to Ancestry or FindMyPast??????
