In my dna matches on Ancestry I have found there was a Rawitscher familly from Krotoszyn. There is a man named Hirsch Leibe Rawitscher born in 1810 in Krotoszyn and died in 1892. Also I have found a Josef Leiser Hirsch born in 1766 from Krotozyn.
My great great grandfather Isidor Margolius married Hanchen Wiener . They lived in Krotoszyn as well.
