The reason I want the image tidied up is because it has flashes of light glinting across it.
I have absolutely no photos of that side of the family except for a few of my grandfather. I can see the chin is similar but it's hard to tell with all those whiskers. My grandfather was clean shaven. There is also an aunt who had a similar nose. I would love to see just one photo pf one of my ancestors from Ireland but the marble bust is the nearest thing I've got.
The archivist at the RCSI took the photo for me but she could find no trace of any photos or a portrait. There are loads of oil paintings in the building and they are all catalogued.
You could look at Wikipedia to find out about busts.
