Van Orin is in Bureau County, Illinois. I know there were Terry's living in Bureau County in the 1880's as one of my ancestor's sisters married a Terry. this would probably be off a generation or so from the Terry you are seeking, though may be helpful to know that Terry family was in Bureau County area. Several of the Terry's are buried in North Prairie Cemetery, which would not have been far from Van Orin. Hope this helps a little in your search.
