Dear Nina, my name is Lee Debnam and I live in Sydney. My father Maurice Debnam was born in Southend, Essex in 1940's and his parents Leah (nee Minden) and Harry (or Henry) lived at 7 Northumberland St, Southend. Leah and Harry died possibly in 1980's in Essex and Maurice moved to Australia with his new family Penny (wife), Nicole and Lisa. Looking for my grandparents details is like looking for a needle in a haystack. I hope this information helps you!
