I am not related to the Von Bluchers but have been researching my Gilberg family line in and around Waren-Muritz. In the Waren Burgerbuch I came across a Gerhard Ludwig Hartwig von Blucher in 1792. Knowing about Gebhart von Blucher and that he fought the French in Waren in 1806 I wondered about the connection with this entry in the Burgerbuch. It appears to say Gerhard rather than Gebhart but the name was so similar it caught my attention.
