Searching for the names of parents of Nathan HAASE (1838-1912 Berlin)

My great great uncle Nathan HAASE was born 5 May 1838 and died January
3, 1912 in Berlin. He lived in Konigsberg and Wormditt, East Prussia.
I would like suggestions on how to find the names of his parents. One
of his sons was the famous social democrat Hugo Haase who was shot on
the steps of the Reichstag in 1919 and died a few days later.

Any suggestions are appreciated.
