Thanks a lot Judy!
My Stanislawa Lukaszewski was born 1882 in Mrowino by Rokietnica/Poznan. It is some 80 miles away from Kleczew. Not far away but here the PoB is indicated very precisely.
If it comes to Eleanor, her father is Wojciech Lukaszewski. It would be Wojciech Jr. as indicated in the records from Ellis Island. Maybe?
Many thanks again!
