Date of photo by Byrne of Richmond?

[ainslie]

I am sorry I cannot post the images but I have a c de v photo of a Victorian lady. 
On the front, at the foot is "Byrne & Co...Richmond."
On the reverse there is no place for a serial number, though I have seen this printed on others by this artist.  Royal arms /Byrne & Co / Photographers to Her Majesty / Hill Street / Richmond.

At the foot in tiny script: Marion. Imp. Paris.

The subject of the portrait died in 1897.  I have seen online images by the same artist with variations, but none identical.

With these clues is it possible to give a date for the print?  Thank you.

Hill Street was known as Clarence Terrace and it seems the name changed sometime between 1883 and 1900, so this looks like the period you need to be looking at.

Thank you.  That narrows the search.
