Thank you, I'll add them to the Brownell family. On the 1939 census, I found dad Joseph, a widower, living with his married daughter Mary Alicia Blackwell and her husband's parents at 91 St Helens Rd., Southend on Sea, Essex but there's no record of his wife Alicia's death anywhere or where she died. Nor of George's sister Harriet after the 1921 census.
I want to say that I am extremely appreciative of all the help, links and suggestions offered to me.
