Hi Dorothyl,
I was going to reply to another post that I saw regarding your family information that you were seeking when I saw this post of yours too.
I believe I know your half sibling side of your family.
Regarding this place in Conwy , it is Dr Garrett's convalescent home in Conwy.
Manchester hospitals used to refer poorly children there , and I believe that other members of your half family also to have spent time there.
If I'm on the right tracks, the name George should mean something to you?!
