I have traced Family tree information on Baltasar's sons Andreas born 1835, Ignatius born 1835 (my tree) and Philipp born 1838. Baltasar and Anna Maria Louisa Damm's 8 children were born and died in Krasna. I've checked these 3 trees and haven't found a trace directly from Martin Karl Erker to Baltasar. It could be that he is a decendant of one of Baltasar's other sons.
I have found that you have the connection to Baltasar in another way. 1. Baltasar, 2.son Andreas born 1835; 3 Andreas' son Phillip, married to Elizabeth Hermann; 4 Phillip and Elizabeth's daughter Josephine Erker married Michael Erker born 1895 Krasna. Michael Erker is the son of Martin Karl Erker (born May 20, 1857, died Nov 11, 1918) and Justina Colestina Nagel.
I'll check further and see if I can find anything more for you.
