Most of my great-great grandparents were born in Germany or Denmark (12 out of 16) and didn't come to the USA until after the 1870s. One of my great grandmothers from the German side, was the first of her family born in the USA, she died in 1987 at 106 years old. She was about 4'-10", was always called "Little Gramma", and spoke with a heavy German accent up until her death. My mother's father's side of the family came mostly from Ireland or England as early as 1703 or thereabouts.
