My suspicion is that the gentleman on the left is John Benjamin Figgis. The Middle photo would be John and either his wife Harriet or his sister-in-law Anna Marie, and his brother Samuel. I would like to think this is so.
The photo on the left above is from photographer Hennah & Kent, Brighton, the middle one above is Bennett, Worcester but I have included it here as it is obviously the same gentleman. The photo on the right is photographer Mayall of London and Brighton.
These two ladies above were both in Brighton and photographed by White.
