His marriage certificate will not necessarily give his age.....are you assuming he married in 1907, Carole?
Dave, if you post all the information you have from the marriage certifcate, including witnesses and occupations, it will give us more to go on.
I have found a few deaths of Henry Hunts in Lincolnshire shortly after 1907, but they are all quite old.
This might mean that he married later in life, or indeed twice??
There is a Henry Hunt on the 1901 census with father William & mother Elizabeth living in Wootton Lincs. His birth year was c1874.....could this be him?
