I note that the Spring 1926 electoral roll shows that Emma Marie Uridge neé Whitaker was registered for the Spring 1926 roll prior to her death. This was the only time she was shown at 205 South Lambeth Rd so it seems that she may moved in with her daughter and son-in-law as well as my great-uncle Bert and his parents only a short time before her death in late 1925.
I note that previously I had the incorrect image against the narrative for her daughter Emily. This will be changed in the next website update.
Thanks to James for this information.
