The collection contains originals and transcript copies of letters, (December 1890 - August 1891), between Dr Edward Greenly and Annie Barnard, from the period of their engagement until their marriage in August 1891. The letters are intense and passionate and reflect the couple's interest in spiritual and theological matters as well as Edward Greenly's work as a geologist. The transcripts were written and edited by Edward Greenly, ca 1935.
There is also a transcript of Edward Greenly's memoir to the life and work of Dr Griffith Evans, (1835-1935), a Meirioneth veterinary surgeon and researcher, entitled Griffith Evans, A Pathological Pioneer.
