I have been fascinated by Constance and Albert for many years, so it is really exciting to read your messages. Albert Pickard was my great uncle (my Grandfather was his younger brother, Harry Pickard born 1879) and I discovered a few years ago that Constance was my husband's great aunt (his Grandfather was Robert Collister Moore the eldest of Caesar Moore's children)...this was quite a discovery!
The little I have been able to discover about Constance is that she remarried in1934. She married Ernest Gelling and she died in 1951 aged 80, he died in 1969 aged 89. I have a photo of her grave if anyone would like me to send it.
