Research Notes:

His name suggests that Graf Markward [II] was the son of Graf Markward [I] but there is no proof that this is correct. The assumption is that Markward [II] was a different person from Markward [I] on the basis of the 24 year period between the years when each was named but this is not inevitably so.
