Hello Jenny,
no, there is no town or village with the name HACKENBURG nor in the former kingdom of Hannover nor in Germany of to-day. Probably "Hackenburg" ist not the name of a town or village but of a farm. Mostly the addition of a "von ..." to a name like MEYER is above all the name of a farm.
Regards
Wilfried
