Hy dear Leon,
I just got your message, sorry I didnt answer before.
I guess you are Marks brother, with whom I am/was in touch.
We know we are related thru the filmmaker in France?
I have lot of information about our family as Im a researcher.
I lost my dear dad last year with 95 years, he told me a lot.
Please write to me to: firstname.lastname@example.org
All the best
