As indicated by the caption, this is an image of Katherine Mackay (Katherine Alexandra Duer (US1797spouse1)) taken circa 1905 with her two daughters Katherine Duer "Kay" Mackay (US1797a) and Ellin Mackay (US1797b).
The caption accompanying this photograph reads:
Circa 1905: Katherine Mackay with her daughters, Ellin and Katherine. Photographed in Katherine's sitting room, this photograph is great interest, as it shows a dramatic transformation of the French walnut room, which has been painted cream color, the mauve damask wall panels, replaced with velvet and hung with the Arras "Four Season" tapestries. Mistakenly identified as made by the Gobelin factory at this time, they had started in the great hall, and then moved to the salon, before finding their way here. The original fitted Wilton carpet has also been exchanged for a Louis XV Savonnerie style carpet
