These two men are often confused because of hand writing. There is a Daniel Thompson from New York that fought in the War of 1812 but was originally from CT. He was married to Susan Ann Bradley and they had 10 children. Here is his obituary. He is buried at Elmwood Cemetery in Detroit.
OBITUARY: Det Free Press 1 Feb 1860, Died in this city on the 31st of January, Daniel Thomspon aged 73yrs. The funeral will take place at the residence of his son Bradley H. Thompson, corner of Hastings and Woodbridge, on Thurs Feb 2nd at 10 o'clock am. The friends of the family are requested to attend. The deceased was one of the pioneers of Mich, having come here in 1825, since which time he has resided in Detroit or its vicinity. Shortly after his arrival in the then Territory of Mich he was commissioned by the US government to open two roads through the dense wilderness which then surrounded Detroit and performed his duties to the entire satisfaction of all parties interested. These roads are now the great thorough fares known as "Chicago" and "Gratiot" roads. During his lifetime he held many public positions and in all of them enjoyed the entire confidence of the community whom he served. He was a warm friend and supporter of Andrew Jackson, and also of Steven T. Mason, first governor of the State, and was a prominent leader in the first gubernatorial canvass of Mich. In 1840 he was elected sheriff of the County of Wayne, to which office he was re-elected in 1842, holding that position for 4 years after which he removed to Dearborn, living there in comparative retirement, but frequently visiting his children in this city. He was always happy to meet his old friends and acquaintances and talk over he occurrences of years gone by. During the last war he entered the army as a volunteer and, with the Company to which he belonged, was stationed at different points along the Canadian frontier, being an active participant in the excitement of those days. At the time of his death he was a member of the petit jury of the Circuit Court and his last illness commenced while on duty as a juryman. The best medical aid was summoned to his relief, but he gradually passed beyond all human agencies, and on the morning of the 10th day of his illness calmly breathed his last.-- Conn.
