Maurice married Elizabeth Mary Louisa in 1800 at St Olave's Church, Southwark, London.
The marriage took place unbeknownst to Elizabeth's father, Rowland Jones, a former president of the Gwyneddigion Society.
[1] Peter Maurice, born 29 June 1803, attended Jesus College, Oxford and became a priest on 13 Oct 1827.
With Owen Jones as a teacher, Maurice learnt to transcribe Welsh manuscripts in prose and verse, becoming a principal member of the Gwyneddigion Society.
A number of transcripts attributed to Maurice are in the Cymmrodorion collection[2] and the "Bardoniaeth" Manuscripts in the British Library.
