Lindynz,
I always think that the newspaper articles make family history come alive; so I started to look at Esau Clark, brother to Adam.
The only article I could find about him was this:
THE GLADSTONE DIVORCE SUIT .
Hampshire Telegraph and Sussex Chronicle etc (Saturday, July 31, 1875;
The above case concerned the wife of a Mr. Gladstone and a Captain Bridgeford. This was a hearing that last 4 days as far as I can see, where several witnesses were brought to show that the above two people met each other, and spent the evening in each other's company, when Mr. Gladstone was out of the house. Maids testified that the blind was pulled up to show Mr. Gladstone was away etc! Anyway then I saw this:
Esau Clark, a wood and coal merchant at Southsea, spoke to having the ferry from Cumberland Fort to Hayling Island from 1852 to 1871. He remembered the gentleman (whose portrait he recognised) being taken over; he was generally accompanied by a lady.
So I looked at the 1861 Census, and sure enough Esau Clark born 1814, Drayton, was living in the Ferryman's house, married to Charlotte, with several children, the youngest Selima 4 & James 2, having been born at Cumberland Fort and Esther, 7 having been born at Hayling Island.
So I think that this is your Esau.
