Despite intensive anoraking and trawling my notes I can't really help you as East Anglia was the Zepps dumping ground.
They were cautioned never to be over the English countryside during daylight hours. Most Zepps made landfall between the Thames estuary and The Wash, if they had come on the wind they would hold station off shore awaiting nightfall before proceeding inland. If on the other hand they had struggled against a headwind it was quite often too late in the night to make it across to London and back out to sea before sunrise.
If the Zepps arrived over East Anglia too late to make it to London et al then they quite often bombed indiscriminately.
