Thomas Cushing Aylwin was a lawyer, political figure and judge in Lower Canada. He was born in Quebec City and trained as a lawyer, including a period of education at Harvard University. He developed a reputation as an excellent trial lawyer, particularly in criminal cases. He became interested in politics and supported the nationalist Parti canadien in their struggles with the British governors of the province. He did not support the armed rebellion in 1837, but defended some of the individuals accused of treason or other crimes for their roles in the rebellion.
