2545. Marmaduke Richmond 7 (John 6, Sylvester 5, Cyrus 4, John 3, Edward 2, John 1), son of John and Dorothy (Hutchinson) Richmond, of Murray, Northumberland County, C.W. (Ontario) Canada.

Marmaduke Richmond's wife, Levina [Terrill], was married to Thomas Outwaters and living with children John Richmond and his twin sister, M. Sophia Richmond, according to the 1861 census. There was also a young Levi Outwaters, age 4, in the household. At this point I'm assuming that Marmaduke died between 1851 and ca 1856.
