Hi again Paul
I think this is your man, I've found another two navel records which I thought were the same person. One said William Dawkins date of birth 1824 place of birth woodnesborough. I looked up woodnesborough and its a village near Sandwich, Kent and on searching 1851 census there is a George Dawkins who was born 1774 in Woodnesborough who is an Agriculturer Labourer, matches father on wedding certificate !!!! Also on the family search website there is a christening record for a William Dawkins Christening Date: 22 Apr 1824, Father: George, Place: Woodnesborough, Kent, England
