Dorothy is listed in the record of her father's funeral in 1598:as having been given "ii yards and a halfe" of black.
Dorothy married Henry Butler.
She passed away after 1619.
Although Tudor Place states that Dorothy married Henry Butler, there is a record for the burial, at the church of St Peter and St Paul, Ormskirk, Lancashire, on 22 July 1614 of "Dorithie Stanley Virg.", that is, unmarried.  If this is the Dorothy of this profile, then Tudor Place must be mistaken.
