   • 1886 October 23, “Cofiant y Diweddar Barch. Henry Rees”, in Y Goleuad, page 4:

     Syr,—Wele yn agos i ugain o flynyddoedd — ugain namyn dwy – er's pan hunodd yr enwog Henry Rees, ac hyd yma mae ei enw wedi ei adael heb gymaint a hyn o goffadwriaeth ar ei ol.

     Sir, it has been nearly twenty years - eighteen, to be precise - since the famous Henry Rees died, and so far there has been little done to commemorate him.

     (literally, “Sir, - See, nearly twenty years - eighteen - since the famous Henry Rees slept, and so far his name has been left without much commemoration of him.”)
