Once again I'm bringing up Guntram den Reichen whom we have conflated with Guntram, son of Hugo Graf im Nordgau (Alsace-122). This previous G2G discussion ended somewhat unsatisfactory concerning the identity of both. Since Guntram der Reiche is considered the progenitor of the Habsburgs it is, in my opinion, an important profile but one without a bio. Since dates and family information are considerably different for the two and for what we have in WikiTree it seems important to decide which way to go so that a bio can be generated and the alternatives discussed appropriately.
Our Guntram (Alsace-122) is born about 904 and died 1 Apr 946. Dates for the historic figures are all over the place so that it seems impossible to discern a birth date. There seems to be agreement, though, that Guntram der Reiche died around 970, possibly 973, and Guntram im Nordgau sometime after 952.
Our Guntram is married to Itha von Montfort or von Calw, the historic Guntrams have no marriage known for Guntram im Nordgau, and name of wife unknown for Guntram den Reichen.
Our Guntram has a son Lanzelin, inexplicably named (Calw) Habsburg, Guntram im Nordgau has no known descendants and Guntram der Reiche has a son Landolt who may have been Lanzelin, Graf von Altenburg, whose descendants became the Grafen von Habsburg.
