Similar to her sister, Jennie, Agnes remains a somewhat elusive person. She lived in and around Dunedin, particularly the southern part of the city her entire life. There is no indication of how she derived a living. There is very, very little detail, but what I can share with you is the cemetery record from East Taieri Cemetery, near Mosgiel.
Agnes is buried with their parents at East Taieri Cemetery, Block DD, Plot 247. There is no grave marker of any description and the Dunedin cemetery database just has a photo of grass.
Her Will left her estate mostly to charity, particularly the SPCA.
