Hi
Just to add to this thread, a photo of John Birmingham was actually discovered last year by accident, it was hidden amongst other family portraits..
The portrait, further information about John about its discovery can be viewed at https://milltown.galwaycommunityheritage.org/content/people/our-milltown-men/john-birmingham/john-birmingham-his-portrait-discovered.
I am currently working on an updated talk about John Birmingham and the legacy of his observatory and spent the afternoon sifting through all his historical correspondence and observations.
Thanks
