Thomas II de Bermingham was an Anglo-Irish lord who died in 1473.
The succession to the lordship is unclear for much of the 15th and early 16th centuries.
According to the annals, in 1426: John, son of Mac Feorais Bermingham, was slain by Thomas, his own brother's son.
When Walter died in 1428, he was succeeded by a Thomas de Bermingham.
The Complete Peerage states that this Thomas was a son of Walter.
