The darker photo shows two Fleur De' Les. They are french symbols of what can be a lily or iris flower. I have one with the symbol in the middle.
The middle image seems to be a torch.
The other photo is a little more difficult but first impression is the symbol of medical doctor, a serpent and a staff. In this case it appears to be a torch but why not color red.
Thanks the house was built by the French between 1790-1805. I understand the Fleur de lis is a French symbol.. It's also used by the Vatican and Jesuits. they just seem Catholic like to me what do you think?
