Hi Mike, I don't know the book from which this is taken but the caption seems to suggest that Mr. Green is discussed in the text. I assume that house referred to is the one on the right. I don't know why no first name is used. I have found John S. Green at Ashted Row in a number of directories up until the 1830s. No number was given - possibly no numbering at this stage. I think he checked out in 1847 which may be when the name was dropped by Bacchus? It was once called Bacchus, Green and Green.
Anyway, the house on the right became No.38 and was the home/surgery to doctors in the 19th century. I have a pic of the house with one pilaster of the adjoining Parliament House.
