Carl,
I started on WIchmann last evening, a couple of things if you could look please,
Most importantly Geni has this profile as WIchmann V. Both Wikipedia.nl and this Dutch encyclopedia here: https://www.berghapedia.nl/index.php?title=Wichman_IV_van_Hamaland have him as WIchmann IV.
Both show WIchmann V as having a short 8 year life
However MEDLANDS and Pattou show him as Wichman V
( I note that Wichmann was both a Dutch and a German name and seem to have quit popular then, here was a WIchmann the family of the Billungen and I’ve seen a parallel descendency with WIchmann I and II in the same time frame.
I updated the death date and location based on the discussions that clarify that Wichmann retired to the abbey on the 799 date where he lived for several more years, dead by 983
Updated the burial location but I’m not quite sure,
1) is a Stife a church building or an ecclesiastical area, and
2) the city Emmerick appears in Germany now but right on the east side of the border. If the border was different when WIchmann was buried and it was a Dutch town then we should use the Dutch name.
I have not found a birth location so can’t confirm what is shown but it seems too generic...
I’ve expanded the Overview tab...
