I believe the name in Poland was PENDZIUCH though it was spelled several ways. The name appears in several Lomza area towns but I cannot see records for your family at this time.
You will not find Wolf in Ostroleka as records for that period do not exist.
If you found their Ship manifest on Ancestry then also look at the UK outgoing manifest. I think the writing is a little clearer though less information is provided.
(Not too far from where they sailed from to the USA)
