Dear all,
Thanks for all the posts trying to answer doctor or quack?
Today I visited Henry Kendall Cottage in Gosford, where Barker practiced as a doctor.
(Henry Kendall was a well known Australian poet and was married to Charlotte Rutter, sister to one of Barker's daughter-in-laws.)
There is a historical museum there but nothing about Barker.
There were plenty of local historical books, of which one (Gosford and the Kendal Country, by Charles Swancott) mentions that there are 2x surgeons and 1x doctor in the area in1854, Joseph Benson Barker being the Surgeon at East Gosford. (note the mixed up name)
With all the posts on this board and this also being confirmed in this book by and respected local historian, I am going to believe that Barker was a surgeon.
The search will go on to find the proof of his qualifications but for now this is where I'm at.
I thank all of you for your help and I appreciate all the pieces of the puzzle that you have provided so far. I only hope that some day I can repay the kindness.
Carna
P.S. JM, Thanks for everything, especially for keeping me true.
