Hello again - well this is a find! Thank you so much. Those two house numbers now make sense because Robert's Will states he was living at 115 Errard Street when the Will was made. The carpenter by the name of F G Carroll and living at 121 Errard Street is Robert's son Frederick George who is my great grandfather. Frederick married in 1891; so depending on which directory you're showing here, his wife would've been living at 121 as well. Yes, I hope for your sake that air shaft's well and truly buried deep underground! Might be a few skeletons under there as well! I wonder if the Council can assist you with an old map that shows the situation of the mine and therefore where Bardwell was standing when he took the photo?
