Sorry for really late response.

While more can always be said, the basic problem (relative dearth of the sources and their trustworthiness) have been formulated in the following questions and answers, and you can check them at the moment:

• How much do we actually know about Anglo Saxon paganism as opposed to speculation based on Christian texts and other Germanic religions? Do we even have any solid evidence of their practices? And is it likely that the goblins and fairies of later English folklore were taken from pagan myths?: answered by /u/Steelcan909 and /u/itsallfolklore
• Why is Norse mythology so well-known compared to other contemporaneous Germanic religions?: answered by /u/Platypuskeeper and me (/u/y_sengaku)
• When did Germanic Tribes start believing in Norse gods and really how did it come around?: answered by /u/BRIStoneman and me (/u/y_sengaku)

As for alleged deities among the Continental Saxons, Old Saxon Baptismal Bow (Indiculus superstitionum et paganiarum) (around 800 CE) and two Merseburg Charms (extant in the 10th century manuscript) are almost all we know about them, and I actually translated whole text (neither excerpts or summary!) in the second linked thread.
