WAS born in Quebec, 5th January, 1806. His father was Welsh and his mother Irish.   His early education was in Quebec under the well-known Rev. Dr. Wilkie.  After passing a short time at Harvard College, he returned to Canada and devoted
himself to the study of Law,  When only sixteen years of age he was interpreter in the Criminal Court at Quebec.  He was called to the Bar of Lower Canada in 1828.
During the troubles of 1837-8, Mr. Aylwin espoused the popular side, and wrote many vigorous articles against the Government of the day.  At the Union in 1841, he entered Parliament as representative for the County of Portneuf.  The next year he became a member of the Executive Council as Solicitor-General for Lower Canada, remaining so till December, 1843.  His parliamentary career lasted till 1848, being during that time twice elected for Portneuf, and three times for the City of Quebec. In 1848, he again entered Parliament, but in two months was elevated to the Bench, being made Judge of the Court of Queen's Bench, and removed to Montreal in 1850. To 1867, Mr. Justice Aylwin continued to be one of the brightest ornaments of the Bench.  He died on the 14th October, 1871, one of those Judges who, though genial off the Bench, was remarkable for stern discipline and punctilious severity when on it.
