Llythyrau, 1899-1917, at Robert (Silyn) Roberts oddi wrth yr ysgolhaig, bardd, beirniad a'r golygydd W. J. (William John) Gruffydd (1881-1954), ac un llythyr, 1918, oddi wrth Gwenda Gruffydd, gwraig W. J. Gruffydd. Cyfeirir at yrfa academaidd W. J. Gruffydd yn Rhydychen; ei garwriaeth â'i ddarpar-wraig Gwenda Evans ac â merch o'r enw Winnie, a'i briodas yn y pen draw â Gwenda; "Miss P."

Gruffydd and his request to receive some of Silyn's poetry; his editorial work; religion, philosophy, politics and personal theories; and his period in the navy and his longing to leave the service. Gwenda Gruffydd's letter refers to her battle to have her husband released from his naval service, requesting Silyn, with the support of "Tom Jones" (most likely Dr Thomas Jones (1870-1955)) to help bring this about.
