Note 097
From Chapter 49 of the Decline & Fall

The marriage of Eginhard with Imma, daughter of Charlemagne, is, in my opinion, sufficiently refuted by the probum and suspicio that sullied these fair damsels, without excepting his own wife, (c. xix. p. 98 - 100, cum Notis Schmincke.) The husband must have been too strong for the historian.
