Sorry been offline since yesterday afternoon.
I've never heard of mundia.com? I'll have google it! Yes Vorwerg is a strange middle name but John Vorwerg (later William) Dobson was named after a George Frederick (or Georg Frederik) Vorwerg, a German who, in 1800 married the widowed Mary Dobson (her husband Robert, a Brewer of Swan Lane, Rotherhithe died in 1795).
Mary (maiden name unknown) had two sons by Robert, John Dobson born circa 1791 and Stephen Dobson born circa 1794. They must of been very fond of their Stepfather George Frederick Vorwerg. Stephen (my 3 x Gt. Grandfather) then named his eldest son Henry Vorwerg Dobson and his second son was my Gt.Gt. Grandfather John Daniel Stephen Dobson took the idea and named his son John Vorwerg Dobson.
I think that George Frederick Vorwerg, later remarried on the death of Mary and lived to a ripe old age, I've found a reference to him as leaving a painting to a local church in his will.
Clear as mud?
Cheers

P.S. Jaywit, I may have to buy more birth certs, good idea!
