My dad was born in Germany and traveled to the U.S with his family a few months after he was born. His parents were from the U.S. but were in Germany due to the Vietnam war. A few months ago I performed an ancestry DNA test and found out that the city my dad was born in 52 years ago was the same town his ancestors were from in Germany when they emigrated in the mid 1800s! Such an enlightening and humbling experience.
