Dumbledore became Headteacher sometime between 1965 and 1971 according to Remus Lupin when he says "I was a very small boy when I received the bite...But then Dumbledore became Headmaster, and he was sympathetic." Ten years before then puts Hepzibah's death between 1955 and 1961.
↑ Harry Potter and the Order of the Phoenix (film), on the Black Family Tapestry, Andromeda is shown to be the second child of Cygnus and Druella. Her older sister was born in 1951 and her younger sister in 1955, meaning she had to have been born between these years.
↑ Sirius Black said Bertha was a few years above him at school. This means she had to have been at least two years older than him but no more than five because she would have left by the time he started. Sirius was born in 1959 which means Bertha had to have been born between September 1953 and August 1958.
