I'm Otilia Lazar, my grandfather is also from Danes, his name was Lazar Ion, and was born around 1920. His parents, unfortunately don't know their name (my grandfather died and I didn't ask him) left from Danes around 1930 but stopped in Braila, Romania because one of them get sick and died, so they remained there.
I'm curios to know more about the family and why they wanted to left all in America.
For information about birth or marriage documents I think the city hall from Danes or Sighisoara is the best place to look for.
I know my answer comes after 10 years but I'm glad to meet some possible family members.
