Looking for Job, lost in Berlin c1870's

[Glen in Tinsel Kni]

Hi all

I have a rellie by the name of Job Goulson (b1821, Lincolnshire) who moved from England to work in Berlin, there are several documents sent back to England for his work ti do with gas meters (he was apparently the manager of a gas works and an ID booklet suggests he may have lived around Kreutzberg).

His wife died in March 1871, his daughter married 25 Oct 1871 at the Evangelische Kirche, Berlin, Brandenburg, Preußen, Germany.

I haven't found any trace of him after this period, can anyone find anything, in particular his death or any trace of his son Joseph Page Goulson, b 1853 in Westminster, or point me in the right direction?
