Annie Baron of Manchester

My great grandmother was Annie Baron of Manchester, born Dec 1858, parents John Baron (1826-1872) and Sarah Jane Simpson (1827 - 1864). They had interesting names in the family that have helped my research, such as Bridge Baron, and Charles Dickens Baron, brother of Clement Simpson Baron. Annie came to New Zealand with her husband, John Lonsdale, in 1904, passing through Sydney on the way - I have his letters, written from the Persic. I can get back as far as Heny Baron who may or may not have married Grace Mercer, but beyond that my tree is hard to prove. So I am looking for well researched family trees with Barons in them, that I can use to support my research.
