I was intrigued by your posting. I have a Samuel Dunkley in my family tree, who was born in 1865. He is as far as I can tell the sister to Charlotte my gggrandmother. She was always rumoured to be connected somehow to the Pram making Dunkleys and this may be the connection. We would need to compare information to check this, which I'm happy to do, and I have more information on their family.
