My sister's husband is really interested in his heritage and his grandpa is first generation born in America. His GRANDFATHER'S parents came to America from Holland. So that makes my sister's husband half Dutch, because his dad is Dutch but his mother is not.
My family has always knew that we mainly came from the Netherlands. Both of our parents are around half Dutch, because both of their parents are. My family even has books about our family and ancestors.
Now the story:
He told my sister that we can't have Dutch in us (at least not like he does) because Dutch people "only have blond hair and blue eyes" Ok dummy. We also have French in our blood (my great grandma is 100% French. Her grand parents came from France. My great grandma I guess would be 2nd generation born in America. BUT!!!
I found out my dad's parents are both first generation born in America and their parents came from guess where... Yep The Netherlands. One set from Holland and one set from a small town. Their last name was even named after the town they are from.
My mom's side my grandpa is also from the Netherlands and also German and Irish. These are all from the books and plenty of investigation from genealogy.
I think my BIL is stupid. He would always bully us, because we just SAY we are from there without knowledge.
My family has blue/gray/green eyes and blond as babies and it goes darker when we get older.
sorry so long. But seriously Because of him having blond hair and blue eyes makes him more than us. The Dutch are also known to be the tallest ethnicity. He is 5'8" My brothers are 6'3" and 6'4". You don't necessarily just have one characterist because you are mostly of one thing. You also have other ethnicity to give you other characteristics.
