There is a very interesting, and pretty complete, tree on Ancestry that has the following information:

Elizabeth Jane Taylor

Married to George Gordon Duncan (1859-1935), 15 June 1884, Port Elizabeth, Eastern Cape, South Africa.

Children:

George Benjamin Taylor Duncan (1886-1943)
James Henry Sievewright Duncan (1888- 1976)
Florence Duncan (1891-1969)
Alexander John Duncan (1892-1980)

Death: 2 Jul 1895, Barberton, Mpumalanga, South Africa.

There's some supporting South African documents that I'm not able to view. But there is a death certificate that confirms her death and the names and ages of her children.

There is also a baptism record for her son George who was baptised in Coleford, 6 June 1886. Abode is Port Elizabeth SA.

There's probably a lot more information in this tree but that's as far as I've read. If you have access to Ancestry, the link is https://www.ancestry.co.uk/family-tree/person/tree/68491401/person/432043100897/facts
