" The tradition was started in 1791 by Philip I who commissioned a set of 6 portraits from John Walters of Denbigh. Amongst others, the portraits commemorate:
Jane Ebrell, house-maid and spider brusher, aged 87;"
I don't think we can assume that her portrait was done in 1791 but it's probably not too far out, and if so, her year of birth would be 1704.
