I wonder if there are any contemporary photos of these men to compare with - e.g. in earlier English newspaper articles etc
I have tired and failed to find any. One of the problems here is that given the circumstances of the men's deaths, they tend not to be discussed even today in Ireland
John Fitzgerald in particular, I have delved into in depth but never managed to unearth a family member who might have a photo.
I found a
photo of the grave of Angliss on this page but not the man
No photos seem to have been published at the times of their deaths, again for obvious reasons.
Having said all that, it would be very difficult to be sure of an identification from a photo. I have tried with the men in Casement's Irish Brigade, where I have comparison photos, but I cannot be sure of the identification of the man in a group photo.
And in the case of the Cairo gang, their faces are not easy to pull out, and their caps confuse identity.
Having said all that, if you have a photo of any of them, I would be very grateful
