Hi Marilyn,

It's possible that this Michal Rotman who has a Page of Testimony at Yad Vashem is the man you are seeking (https://yvng.yadvashem.org/nameDetails.html?language=en&itemId=558549&ind=1).  Unfortunately, it doesn't have his parents' names but he was living in Ostrow Mazowiecka which is not far from Zareby Koscielne.  Hopefully this helps.

Regards,
Aaron
