I see your point.I can find little bits and pieces about Robert Butler, but no birth record.
Robt appears to be on the voters list for Victoria in 1875.
And the Voters List 1898
Butler, Robert, 18 Kingston St, James Bay, Printer, VicC
the following may or may not be connected to your family but you might hold it in your back pocket for the moment until you find out.

in Williams' Vancouver & New Westminster cities directory, 1890, pb. 16Robert Butler is listed as the Foreman of the Queen's Printers in Victoria and as the Assist. Supt. in Williams' illustrated official British Columbia directory, 1892

Butler, Miss j, dressmaker, 26 Parkington
Butler, JohnWm, carpenter, Smith & Elford, 37 Victoria cres w.
Butler, R.J., PO Clerk, 114 Menzies (another good possibility for a relative)
In the same directory where people are listed by address
On Kingston St, from Menzies to St. Lawrence street on the South side (#18) are listed: Robt, Fred and W.A. Butler(so I would expect these three men are related in some way because they are all working for the Queen's Printer it appears)
I expect his parent's names should be on his marriage certificate.Do you have it?
