Hi Patricia, Welcome to the forum. I am fairly new myself.
I used to live in Gopsal Street . I spent a very happy childhood there. Our family moved from there to Sheldon in 1968. The Eagle and Ball was one of many pubs used by our families. We had The Kings Arms, The Railway, The Black Horse and The Duke of York I don’t think my post will help you in any way but I just wanted to mention to you that “I was there”. I do not know any history on the pub I’m afraid but I do know they had great Christmas parties for us local children. It was a great area, with lots of relatives living by us. #7 is how I remember the pub. It looks quite different now, they have done a wonderful job on the refurb. It is used by the Students . There is a fab photograph on the site somewhere, I will try and find it for you. I haven’t been down there for a look for a few years, though we are regular visitors to town via Curzon Street. (before lockdown of course). Unfortunately, little is known about Gopsal Street, Howe Street and Cardigan Street, so I got very excited when I saw your post. On the plus side I have found great pictures of Curzon Street, Belmont Row, A B Row and surrounding streets which have meant so much to me. The team and members of BHF do a wonderful job in providing information and photographs for us Brummies. I cannot thank them enough. I am sure they will be able to help you with your research.
Good luck and thank you. Hope this post is not too off thread. Kind regards, Sue
