[1] She held de Braose lands and castles in her own right[verification needed] following the public hanging of her husband by the orders of Llywelyn the Great, Prince of Wales.

Eva's husband was captured by the Welsh forces of Prince Llywelyn the Great, in fighting in the commote of Ceri near Montgomery, in 1228.

Prince Llywelyn wrote to Eva shortly after the execution, offering his apologies, explaining that he had been forced to order the hanging due to the insistence by the Welsh lords.

It is recorded on the Close Rolls (1234–1237)[7] that Eva was granted 12 marks by King Henry III of England to strengthen Hay Castle.

By the end of that month, she had a writ from King Henry granting her seisen of castles and lands he had confiscated from her following her brother's revolt.
