Hi Hugo
Thanks for taking the trouble to take those photos for me, they brought back so many happy memories for me, I loved being at Nain and Taids house, Sunbeams, and I remember the cul de sac in huge detail as we played out the front for hours, I think I learned to ride a bike there! I think the house was no 8. As you come down into the Cul de Sac from Howard Road it is in the row facing you. there were two semi circles of grass with trees - one on the right had side (by the narrow cut through) and one on the opposite side (the left hand side). Sunbeams was by the one on the left hand side (with the school field behind it). They were all semi detached and it was on the right hand side. And I glad your brother does not recall a train running at that time, as he was born the year after me, and clearly my memory could be right on this occasion.
Anyway as you said it would be fine to post some photos on here, I have taken some screenshots of some of the many old photos I have of Llandudno and the family. Many I do not know who they are of, or the occasion. I have one that is of an official street party in Howard place, it must be post 1941 so it could be the end of WW2, but my mother is seated on the right hand side, with dark hair, the lady in the row behind with round glasses is her mother/aunt, and Richard Benjamin JOnes is standing on the left:
