[7] The identity of Anna Maria is uncertain, she is called Anna Maria Delagard, "sister of William Delagard of Bombay", and "grand-daughter and heiress of William Draycott of Chelsea, county Middlesex"[8] "and of Sunbury Court in Middlesex".
Her gratitude to Lady Jane her benefactor is recorded on an inscribed monument she erected to her in St Mary's Church, Sunbury, where she was buried, but with no stated indication of the relationship.
