Hello Mary, sorry to be so long getting back to you.
Alice Jane and Esther Elizabeth were both sisters of Robina Catherine Moore nee Collister, and of Thomas who was my gt grandfather. Alice Jane was born in 1871 so could the sampler perhaps have been made for her by her older sister Esther Elizabeth, or a third party?
John Collister and Esther Clague had eleven children in all in Santon:
Margaret Collister, 1854
Esther Elizabeth Collister, 1858
John Collister, 1859
Anna Collister, 1861
Thomas Collister, 1863
Richard Clague Collister, 1865
Charles Collister, 1867
James Collister, 1868
Alice Jane Collister, 1871
Robina Catherine Collister, 1874
Robert Charles Collister, 1875
I can email you more information on Robina's family if that would be of interest. I also have pictures of Robina's brother Thomas - I would love to see your picture of Robina and Caesar if you are willing to share.
I'm looking forward to seeing what you have on Robert Coillister Moore.
