The oldest traceable ancestor of the family Dormans is Mathias Dormans, who married in 1597 in Heerlen. It appears that even in the twentieth century near all relatives were born in South-Limburg. The very extensive lineages of this Limburgian family need a clear overview . From Mathias, I have traced the first four generations from 1597. About 1700, five lineages emerge, respectively Petrus Dormans from Schimmert, Mathias Dormans from Nuth, Petrus Dormans from Schinnen, Mathias Dormans from Schinnen and Nicolaas Dormans from Brunssum.
