Mary Ellen Bagnall-Oakeley (1833–1904)[1] was an English antiquarian, author, and painter known for her work in Bristol and south-east Wales.

[3] The senior John Bagnall had been established the firm, bringing five of his sons into partnership with him in 1828, the year before his death.

[4] Mary Ellen Bagnall-Oakeley was a member of or associated with a number of societies in England and Wales.

[5][6][7] On 8 January 1891, Reverend William Oakeley was elected to membership of the Clifton Antiquarian Club, based in Bristol.

The society was founded in 1876 and, like the Clifton Antiquarian Club, offered a programme of lectures and excursions.

As mentioned above, women were allowed to join the excursions of the Clifton Antiquarian Club;[9] Bagnall-Oakeley actively participated in their investigations rather than simply accompanying the party.

[20] The tumulus at the site Heston Brake in Portskewett was opened and examined under the direction of the members of the two associations.

[5] The bequest from William Jones to the town of Newland had also created a lectureship, which was held by Reverend Oakeley.
