For certain we are related to one another.
My Father's family came from Romania, too. And, they also settled in Chicago. However, they arrived earlier, they arrived in the late 1800's.
They also have/had relatives in France who I have spent countless hours and telephone calls trying to track down in or around Paris...to no avail.
We have been working on finding any family thread and I am thrilled you wrote back as you 'for certain' can solve and answer many of our unanswered questions.
With warm hugs to my newly discovered family member,
