NGC 6996. This is a loose cluster, or rich region of the Milky Way, in the northern part of the North America Nebula. It has often been confused with NGC 6997 (which see) in the cluster catalogues, but the position from JH's single observation seems to be pretty good.
However, JH was actually looking for his father's VIII 82, which eventually entered the catalogues as NGC 6989 (which see). As I note there, the positions that JH had when he was pulling together the GC are far enough apart that he made two different clusters out of the observations.
I (1970, Griffith Observer) and Brent Archinal (1993, "non-existent" RNGC clusters monograph) present observations and further discussions of these objects.
The RNGC (Sulentic and Tifft 1973) notes that this is a open cluster.
