Johan is my 3x great-grandfather on my father’s maternal line. His marriage certificate in Amsterdam in 1802 to Elisabeth Bannier, states his birth in Osenbruk but his parents had died and were not listed. Brother was Harmen Hendrik Hulsman. That’s all I know. Can anyone help? I would like to continue this line back further but I need some names. Thank you!

Overleden in Nigtevecht op 8.7.1845: Jan Hendrik Hulsman, tuinman, 71 jaar, echtgenoot van Elisabeth Banier.

Johan Hendrik Hülsman(n) komt uit Ueffeln (Osnabrück). 

Yes, thank you. Can you tell me who his parents are? Bedankt :)

there was a sister as well: Anna Maria who married Johan Hendrik Liera in 1788 [here]; Herman Hendrik married in 1799 [here] - none of the marriage records mentioned their parents, and neither does Harmen Hendrik's death certificate. He passed away on 28.06.1827 in Sloten [here]

And there's Jan Herman Hulsman who married Catharina de Ruijter in 1781 [here] and Swaantje de Moer in 1788 [here]

Thank you, that’s helpful. Such mysterious parents! I will check the siblings and see if anyone has parents listed. Appreciated!
