[ANSTHRLD] Looking for Middle Low German name sources

[Richard Culver]

Greetings all!
 
  I was just curious what there is available for names in Middle Low German in the 13th Century.  This is for me personally so no pressing time schedule.  Texts in German are fine.  My interests of late are shifting from Old English to other Germanic tongues, though I still enjoy it.  Once I finally get some free time from grad school I want to work on sections of the Sachsenspiegel and looking forward to messing with a tongue I am not so familiar.  This might become my main persona, pulling Wihtric out for early events or court only while fighting mid-period.  I would like to come up with a good name for that as well as a new, second device.
 
Thanks,
Rich/Wihtric/whatever I pick.
