- From the Evening Express (Second Edition) dated 28th April 1898
"LOCAL POST OFFICE NOTICE. On and from Sunday next, May 1, the letters, &c., and parcels for Godrergraig Village, Church-road, Chemical-row, and Pentwyn-row will be delivered from the Godrergraig Sub-Post-office at seven a.m. on week days, and over the counter—to callers only—from eight to ten a.m. on Sundays, instead of from Ystalyfera R.S.O., as formerly. The correct postal address for Godrergraig and the places named above will be, "Godrergraig R.S.O., Glamorganshire," and the public are requested to inform their correspondents accordingly, as the misdirection of letters, &c., will probably cause delay in delivery. "
