Forebear of Mengin Le Clerc
Johann von Mengen, Judge of Sierck
A judge of Sierck recorded in the same year as Mengin Le Clerc's earliest surviving act.
Johann von Mengen, Judge of Sierck, appears in 1355, the same year as Mengin Le Clerc's earliest surviving act of sale. The coincidence of date and region is suggestive, but no charter has yet been identified that proves a familial relationship. He is included here as part of the ongoing research context.
