Thanks Sandra & Sue ... you are both on the same track. I think you are right and the Eleanor Maud on 1881 census could be Henry & Alice's daughter (as it says sister in law). I had taken it that the wrong info was on Census. You have both come to the same conclusion so will go with your expertise. Yes, we have traced that a brother & sister with surname Monkhouse married brother & sister Corrin.
I notice in my paperwork that I don't have a 1881 Census for Henry & Alice (got 1891 & 1871 for them) ... to try and think why their daughter was living with Annie & William.

I admire you both for coming to the conclusion of Henry & Alice (Bromley) so quickly ... it took a novice like me about a day to string all this info together ... and you experts find stuff just like that!

Thanks again ... Barbara
