Griffith began contributing articles to the monthly
Y Cronicl (
The Chronicle) journal, established by his uncle Samuel Roberts (Llanbrynmair). He later joined the staff of
Baner ac Amserau Cymru, the most popular
Welsh-language newspaper at the time. He later became the London correspondent to the paper and wrote under the known at his pen name "Y Gohebydd" ("The Correspondent"). Like the paper's owner,
Thomas Gee, Griffith was a keen libertarian and championed radical causes back in his homeland, including the defence of
Nonconformist causes. He was one of those responsible for reviving the
Honourable Society of Cymmrodorion in 1873. He also played his part in establishing the National Eisteddfod of Wales. ==Bibliography==
