Hi there - I do have this man in my tree (not at my computer so this is from memory which further confirms Royd's statement that we spent years and years trying to sort them out so that it's engrained in my head).
I think this man is the son of my Richard Cork/Cooley and appears in my tree - thank you for the record I will see if I have it as a source for him.
And just to say that if anyone reading this can find the Cork family in the 1851 census somewhere in Kent or Surrey, Royd and I will fall on your neck with glad cries of joy. (Richard snr, Jane snr, Richard jnr, Sarah, Jane jnr, James, Stephen - travellers)
