Kaher Family - Gruenstadt, Germany

am looking for any infomation on Johann Peter Kraher married to Louisa Scharmann. I would like to know their birth and death dates and where they lived. I know that Louisa was born in Heidelberg, Germany. Johann Peter was a teacher in the Loewenburg on Bang Street, Gruenstadt, Pfalz, Bayern. I would like to I receive any verification documents that he was a teacher. I can't find Bang St. on maps. I would like to know if they had other children - I only know of , Johann Phillip Kraher born 1791 and married Justina Hahns Furst (widow), I do not know the date of their marriage. They had 2 children that I'm aware of Juliana born May 2, 1826 in Gruenstadt (I do not have a death date or place for her) and Johannn Phillip born Nov 9, 1827 and died Nov, 9, 1827 in Gruenstadt. I'm assuming he was still born and that posibbly his mother Justina died in childbirth. I would like to know for sure.
Johann Phillip later married Juliana Naeher on 11/19/1828 and had 5 children, born in Gruenstadt. I know 3 of them (Johann, Jakob, Gertaude) immigrated to the U.S. Need info on Franiska b: 3/17/1831 and Charlotte b: Jan 22, 1836. I have no record of them immigating to the U.S. They were born in Gruenstadt.
