Hamblin's personal life was controversial. Although he was "noted for his correct business habits, promptitude, and open-heartedness", he was a well-known philanderer. Newspapers and rumours alleged that he had many sexual affairs. In 1831, his wife filed for divorce after returning from a tour in Europe; this was finalised in 1834 with the condition that Hamblin was not to remarry as long as his ex-wife lived. Hamblin continued his womanising undaunted; he saw a young actress named Naomi Vincent for a time, and she even came to be known as "Mrs. Hamblin". When she died in childbirth in July 1835, Hamblin entered a relationship with playwright Louisa Medina.
