Hi Rod,
Thank you - Sandwell Street for sure
If you look at google maps (or this:
http://surry-hills-nsw.street-map.n...sandwell-st/)
the little road running between Sandwell and Fitzroy Streets is.....Farnell Street

As a small aside, the 1887 Sands Directory has no listings for even numbered houses in Sandwell Street (page 19 of the pdf)

I found the undelivered letter list while looking for Abdul. The search page is here:
https://trove.nla.gov.au/newspaper/?q=. I searched Abdul Surry Hills, clicked on the link to the Government Gazettes and saw there was a link to returned letters for 1892. Clicked on that and had to use ctrl+F and searched the page for Abdul.
There were only two matches, the one in the search bar and the one on the page. Hit the down arrow in the find box which brought up the link to 'Continued on page 6290', clicked on that and there it was! This will all be browser dependent of course but the gist will be roughly the same.
The reason I think it's Dari is because I searched "goodfoor" (including the inverted commas) in google and found a Ropasd Goodfoor in Afghanistan. I searched for Afghan languages and looked at the Pashto and Dari scripts. The latter looks far more likely than the former.
Hi Erilaz,
Yes our National Library is such a fabulous resource and thank you for posting the link
I've looked there countless times over the years and have saved many maps for future use. A lot of streets in Sydney city have disappeared, been realigned, renamed etc. Other historical and also parish maps can be found here:

Thank you all, what a wonderful community we have here

So, anyone know how to read Dari
