I have attached 3 photos.
On one you can see a map showing that the Dennyholm (street) ran parallel to Newton Street but was on a level at the back and beneath the street. (next to number 836 on the map). The mill was a bit further back.
The other two photos show the entrance to what was “Dennyholm Street” with a very long row of houses. We can only see the first house on Dennyholm Street on the colour photo which is sitting down from of what appears to be the back of a block of flats which are built upwards to Newton Street. The older photo shows a concrete shed in front of the same first house a little bit closer.
I initially thought that Dennyholm street would have been the blocks of tenaments built up to Newton Street but one of the North Ayrshire Directories of that time describes them as “a long row of houses prone to flooding.” The census of 1921 shows them as having only 2 rooms each.
The area has been completely replaced with the Dennyholm Wynd Housing Estate although on Google Earth you can still see the same street, which is more like a lane now with those yellowish grey flats beneath the ground level of Newton Street.
In the 1900s the street had shops and a school. Dennyholm Street no longer exists and is simply the river walk at the back of Newton Street now.
