Yes, she certainly had tragedy and misfortune during a long and hard life. I wonder what she did for entertainment in her few hours off, theatre, cinema or just walks in the park. She started working 'in service' and I suspect that's how she continued. It would have given her a roof over her head, a crust and a few pennies. Perhaps she just wanted a simple existence. In 1939 at 46 years old, she took up with Frank Harling, a house painter and they stayed at about half a dozen addresses together. I had a look at some of them on Google Streetview and they look as if they would have been beyond her means. From that I surmise they were 'in service' as a husband and wife team. Hence Adelaide adopting his surname.
I don't think her father would have been very supportive. He rarely crops up anywhere in the records. Looking at the workhouse Infirmary records at Adelaide's mothers death, he is noted as being homeless. I still haven't found a record of his death. He was my Great Grandfather and I still have no idea what he died of, or where he's buried. Most likely he died in the street and was given a paupers burial. The search continues.
