I was most interested by your post about Amelia Treeve and Robert Lillicrap.
Amelia belongs to a branch of my family that currently intrigues me. Her mother, Matilda Impey, married Capt Richard Treeve in Cornwall in 1813. Her father, Capt Michael Impey, was the eldest son of Sir Elijah Impey, the Chief Justice of Bengal during Warren Hastings' time there. Her mother, Henrietta Knight, was the natural daughter of the 1st & last Earl of Catherlough.
I descend from Henrietta's elder brother, Robert Knight, who was Lord Catherlough's heir. He inherited some 7000 acres in Montgomeryshire and Warwickshire, and lived very comfortably in a house in Grosvenor Square. His daughter and heiress married Edward Bolton King, of Chadshunt, Warwickshire - they were my great-great-grandparents.
The Impey/Treeves were known to the Kings as poor relations, but something seemed to go very badly wrong with them. Amelia's younger sister, Marion, had an illegitimate daughter in 1850 - possibly/probably by the local vicar, Rev William Corbet le Breton, who was Lily Langtry's father. The daughter left for Australia in around 1875 where she led a pretty miserable life. The whole Treeves family seem to have disappeared from Jersey about that time, and Marion Treeves (now Searle) next appears as a children's nurse in Islington.
Can you throw any light on this? Where do you fit in?
