Wehner, Freise, Gerlach, Gollnisch

I am looking for information on these families that lived in Liegnitz
and maybe Breslau. The last of my mother-in-law's family (nee Wehner)
died in 1948 somewhere in Schlesien. I have reached dead-ends on this
so an help would be appreciated.

I have documented what I have at :
