I've posted below my Llandudno family branches. My Gt Grandparents John and Ann Jones moved to Llandudno from Welshpool in the early 1870s and their children permeated every corner of the town. The second list is my family on my mother's side, my Nain's children - just one of the well known Llandudno branches:
