I think I've found Charles in the 1921 census name down as Bramo. Living with his uncle and aunt William and Mary Bennett in Islington plus others.
Do we know which one is Charles's relation, William or Mary?
Possibly Elizabeth Bliss / Brams mum, and Charles's granny?

Is she the Mary Bennett born Maidstone in Islington in 1921, and thus Charles's great aunt?
