Hi Deirdre,
Thank you for asking such a simple question, my efforts at trying to find Albion Terrace has been quite an eye-opener.
Can you return to Old-Maps and enter the coordinates 308966 and 192600, when the map settles down firstly select the 1876 1:2,500 map, you will see an area of forestry & fields with the map icon/ marker centred on field number 92 and the Cil-fynydd Inn a little to the left (west) on the banks of the Glamorganshire Canal. It would be helpful if your were to click-Off the Print Extent overlay and also expand the map to full screen, use the + & - buttons below the N, S, E & W buttons to zoom in to the best image map that is available
Next select the 1:2500 map for 1900, what a difference twenty five years has made! You should now see an Albion Villa under the map icon/ marker. The Railway has arrived, Albion Colliery has been developed and there is the beginnings of quite a substantial village, however, I can't see an Albion Terrace.
I next tried the 1919 1:2500 map but still couldn't see Albion Terrace, but this was an interesting exercise in seeing the effects of the arrival of the railway upon a formerly rural community in such a short space of time.
Thankyou for asking the question, JohnG. Swansea.
