Career
Mary Dillwyn was the younger sister of the more widely recognized photographer John Dillwyn Llewelyn (1810-1882) who developed new photographic techniques, and Lewis Llewelyn Dillwyn, the father of Amy Dillwyn. Most of the photographs taken by Dillwyn are small calotypes from the 1840s and 1850s, making her the first female photographer in Wales. Her images are more spontaneous and natural than those of other photographers of the period.
Mary died at Arthog, Meirionnydd in December 1906.
