Genealogy / THE MEANING AND RESEARCH OF MY POLISH LAST NAME, SURNAME? [4500]

my last name is Jostenski but we can find no record of anyone else having that name in Poland or in the US. We think they messed it up at Ellis Island. Any ideas about other possible spellings or related names?

Genealogy / Why are some Polish people dark complected, and others very light [511]

my family is polish and there is definitely a mix. We all have dark hair now, but my dad and his brother were born blond. My grandmother and I both have olive skin. My dad and I also have course, curly hair that nobody else in the family has.
