Hugo ... yes, that could be her. I remember it was a Welsh name but I cannot remember the surname. She did work in Colwyn Bay, but I cannot remember where. I think she was one of two daughters, her father worked for Bodnant as the house was part of the estate, and in those days they were rent-free (tied cottages) for Bodnant employees (as was the house I lived in). It was a black A35, but many of them were!
That property, and Croesau Farm at the nearby crossroads, are at the most northerly point of Bodnant Estate. Dyto, at the southern end of the wide part of the A470 towards Llanrwst, is the most southerly point. Croesau was sold to Henry Pochin (see below) by someone with the same surname as me and who I think could link into my family tree, but I've not quite found the connection!
As a complete aside, the Bodnant Estate comprises about 25 farms and cottages as well as Bodnant Hall and what is now Bodnant Garden ... purchased in 1874 by Henry Pochin for the sum of £67,500 ... his daughter Laura became a McLaren and that is the family name still there today, four generations down the line from Pochin.
Going back to the original enquiry and reference to walking to Pensarn, it would be quite a hike but in those days people did walk such distances without the need for wheels.
