If you are talking about Philip H. Hitchcock & Magdelene Margaret Mary Brandow of Walsingham Township, Norfok County, the death register was just for Mrs. Philip (Magdelene) Hitchcock, not for the both of them. Philip was missing from the 1861 census even though his wife was shown with some of her children. One of these children on the 1861 census, John, was only a one year old so Philip either died between the time John was conceived and 1861, or Philip deserted the family. From the 1881 census onwards his wife was shown as Widowed.
There's a photo of her tombstone here under Margaret:
