Try to find the spot where the photographer was standing.
Couldn't find Lady Louisa on Wikipedia. Her father's and her husband's pages mention her as Lady Louisa Caroline.
From this page I gather there was a part of the Munster Blackwater, that her father was responsible for (see entry under: Lismore Weir 1898).

The bridge in "Circa 1910" - www.waterfordmuseum.ie/exhibit/web/DisplayImage/K0mLp7dWl...
"An interpretation board [on Lady Louisa's Walk] provides some history of Lady Louisa Cavendish. Eldest child of the 7th Duke of Devonshire, when her mother died in 1840 at age 28, Louisa, then only 14, took over the running of the household. A lover of nature and walking, she improved the gardens and created many trails along the Blackwater, some of which have since been subsumed by nature."

One of her brothers was Lord Frederick Cavendish, a victim of the Phoenix Park murders in 1882 - en.wikipedia.org/wiki/Lord_Frederick_Cavendish
The bridge is gone, but the stone piers are still there in Streetview
It is just about a mile from Lismore Castle.
It looks like the conifers on the left are still flourishing.
