It may be possible to confirm family relationships with Hans Jacob by comparing test results with other carriers of his Y-chromosome or his mother's mitochondrial DNA.
However, there are no known yDNA or mtDNA test-takers in his direct paternal or maternal line.
It is likely that these autosomal DNA test-takers will share DNA with Hans Jacob:
Looks like he just had a double name, which we see more in the Netherlands as well, so his name was Hans Jacob (no middle names), and his patronymic (LNAB) normally would be Coenraets , his father did not use the Last name Hartje or Hertje at the time of the baptism.
But will look for more sources to see what names he used himself
