William Gibson Quinn died in 1974, in Florida, and was buried in the family plot. He was the last person to be buried in the Old Burial Ground. Earlier coffins were small; his modern one was too large to be contained and rests partly outside the plot.
William G. Quinn was the son of William Alexander Quinn, a barrister who died 1892, and Jennie Robinson, who had graduated from Mount Allison Ladies College in 1887. He was a shrewd businessman and an active Mason, and was described as a millionaire. He never married. At the time of his death, he was maintaining the family home on Brunswick Street, Fredericton, but living much of his time in the United States.
