In the early battles, serving food and drink from the rear guard but in the later battles serving as a surgeons' assistant. A most poignant example of Maria's service to the army comes from her own words in an interview from 1881. In Kingsford's 1887 multi-volume set, "A History of Canada", the death of Charles Lennox is reported partly based on an interview with Maria Hill. Conducted in 1881 by Mr. Walter Shanly (and his brother) just 3 months before Maria died, she describes the retreat from Chippawa to Cornwall. After the war, in 1818, Maria and her husband, Andrew Hill, were reportedly boarding a ship to return to England when they were offered land and a years' provisions to create a settlement for veterans of the 100th Regiment of Foot. Sgt. Andrew Hill supervised the cutting of a road (later named Richmond Road (Ontario) one of the oldest roads in Ottawa) from Richmond Landing to settle Richmond, Ontario. The original road, followed the old Chaudière portage trail and the course of the present Richmond Road.,  Maria and Andrew later opened an inn and tavern in Richmond, Ontario at 3607 McBean St where a smokehouse still stands and the foundations of the tavern underlie the existing house. It was there that Charles Lennox, 4th Duke of Richmond and Governor General of Canada, spent his last morning, having a breakfast prepared by Mrs. Hill and complaining to her of an odd feeling in his throat, before dying of rabies from a fox bite two months previously. After passing away at the house of Dr. Collis, a former surgeon to the regiment, the Duke's body was brought back to the tavern where Maria prepared the Duke for his final trip to Quebec City for burial using the Duke's own quilted bed covering as a shroud. After the visit, the Hill's tavern name was changed from the 'Masonic Arms' to the 'Duke of Richmond Arms' in honour of the visit. Andrew Hill & Maria had two children, Jessie & Margaret Lindsey Hill. Andrew Hill died in 1830. Maria remarried Andrew Taylor, a Sergeant from the 100th Foot. They lived the remainder of their lives in Richmond, Ontario. Andrew Taylor died 29 March 1879, aged 79 years and Maria died 11 September 1881, aged 90 years. She left her estate to the St. John's Anglican Church in Richmond for a new church spire. Maria and both husbands were eventually interred at the National Beechwood Cemetery in Ottawa in the family plot of Edward Malloch II her son-in-law.
