Algernon Curtois' photograph album is held in the Lincoln Central library. Many of the photos therein are not labelled, but a few are.....

Atwill Curtois Anne Henrietta Lee-Warner

Three of their children:

Mathilde Edith, at 16 Florence Isabella Huntley

The above pictures are labelled. The ones below are not, but looking at them I'd say the first is another of Mathilde Edith, the second a much older Anne Henrietta (look how she's dressed - she was a widow for 30 years), and the third.... well, maybe a younger Florence Isabella, or maybe another one of the daughters (she's got the chin!).
