From Tony Woods Combat Claims website, the only nightfighter active that night was as follows:

26.11.43 Major Wilhelm Herget Stab I./NJG 4 Lancaster  N.E. Frankfurt-am-Main: 5.000 m. 20.08 Film C. 2031/II Anerk: Nr.Fo.

I don't have the info on all the losses that night, there may be others due to flak or as in your case, unknown.
101 Sqn as you probably aware was a Special Operations unit with an extra (usually German speaking) crew member who would try to decoy the nightfighters away by broadcasting as if he were a German controller and send them elsewhere.
Hope this adds a little. 3 shot down for a Berlin raid sounds very low, so they obviously did a grand job diverting fighters away, if that's some consolation.
