[Ger-Poland-Volhynia] Spelling of Names for Database

[Leo S]

I am preparing a  family gedcom for submission to the Society for entry 
in the Pedigree Database. While editing the information before sending 
it I have noticed some anomalies in the spelling of family names within 
individual families. The differences are between the family name 
recorded in Polish church records and the name as recorded by 
immigration clerks on landing in North America. The altered names then 
remained in use on all records and documents by those who immigrated and 
all descendants born here carry the modified name.
My question then is which spelling of the family name should be entered 
in the gedcom - the Polish spelling, the North American spelling or both?
