I am a great grandson of L Henrich deHaan who lived in Brunssum Limburg in his last days. My grandfather was Hendrick H. deHaan who married Albertina Josephina Raadschelders-deHaan they had three girls.
my grandfather had a sister Hetty deHaan-Maas and she had a son, i believe they lived around Brunssum aswell. I have done some searches but with little success but thought too see if there was any connection through your family research .
thank you for your time
