Dear Adam and Moishe,
Belated thank you for providing the information on LANGSAMS, DNA and rabbinical lineages.
I am quite behind the curve when reading DNA stats, but hopefully one day there will be additional male LANGSAMS who can share more insight into the possible connection between Pesach and Mendel LANSAM families.
