I will ask the gro for a reference check on the Ellen Otter, just to rule it out, as her Father Dennis was born in Radcliffe also Notts.
As far as we know, if the census is to be believed, and it is our Ellen, she was born in Portsmouth, and her father is a royal marine. What we know as fact from her wedding cert, is that her father is Dennis. Anecdotally we knew that this branch of the family had come from Nottinghamshire somewhere.
But there are a lot of Otters around this area at that time, and particularly around Retford, and again Basford is close by too.
Thanks for all your efforts.
