Unexpected new branch in my family tree

To whom it may concern!

I am contacting you because I see a new branch joined to my father's family tree.

Georg Lamm, Budapest, Hungary (1921 - d)

Probably it was a mistake to join this branch to Béla Lamm.

Would it be possible to clear the situation or reach a data manager (I can not reach Balázs Déri) or get into contact with the data owners of this new branch?

Many thanks in advance.

Sincerely,

Peter Lamm
