Don't know if this is at all helpful, but the 1939 survey lists the following at 52 Campsbourne Road, Hornsey
Frederick Dean 15 Sep 1884 Male General Labourer Married
Alice V Dean 27 Jul 1887 Female Unpaid Domestic Duties Married
William C F Dean 12 Apr 1913 Male News Agent Ass Shop Manager Single
George A Brooks 30 Sep 1863 Male Retired Carman Single
Campsbourne and Oakfield Roads are hardly adjacent, but at least both are Hornsey and people move about. Might the above Frederick be a relative ... names often run in families.
Good luck in your search.
