The Dulmage family originated in Germany, whence they came to Ireland in 1709. Here David was born in County Limerick in 1746. Life in Ireland was evidently not to his liking, so when the opportunity arose, he came to America with a group of German people. His wife, Mary Jennings , was born in Lancaster County, PA., in 1747. During the War of Independence, he fought for the British, and as a Loyalist emigrated to Ontario when the war ended. Three children were born in the United States before David moved to Prince Edward County and settled at South Bay.

Margaret Dulmage, who was born in 1773, married Augustus Wright. Their oldest child was the Rev. Daniel Wright. The Dulmages and Huffs are related by marriage to the Allsions and Hoovers.

One of David's grandsons, William Z. Dulmage, held the position of Justice of the Peace for a great number of years. David's second son. Edward was renowned for his hunting prowess.

Edward's son, Sheldon Dulmage, served in the Light Horse Cavalry in the Rebellion of 1837. He lived in South Marysburgh for five years after he married, then moved to Athol.
