79 Grafton Street...
... was the Dublin School of Photography and Studio of Frederick Holland Mares.This gives us a much narrower dating window for this one than 1860-1883, as Mares moved to 118 Grafton Street in 1875.
The businesses that are clear are:
74 J. Goggin (Queens Carver?)
79 Cartley? (and Dublin School of Photography / F.H. Mares)
81 To Let?
