Thank you DJ and everyone esle for all your help on this.
My head is in a spin going round and round the streets!!!
I feel the house is not there anymore..but it still remains that the bible was found in a house in that area some 20 years back.
My gr gr grandmother (Susannah Harris) was the one who lived at no 10 Watts yard 1881 with two of her sisters living next door, but later in 1891 she was living in Grove St, North St Giles (Today I believe this is in the area of where Turl Street meets High Street) and then in 1901 South Parade, Summertown.
My Gr Grandparents Annie and Eli Ewers (Susannah Harris and Eward Ewers son) son in 1934 were living at 3 Chaundys Place, Oxford as a Baker. Today the Westgate Shopping Centre sits on this site.
Re-development is not a new trend I feel

The bible seems not to have been handed down through my gr gr grandmother Susannah ...but one of her siblings..but who?? And who lived in that house that was cleared??
Once again thank you to everyone who has been helping me on my search
