The unsourced profile of Mary Barker was apparently created to supply a mother for Thomas Chappell-74, whose father is considered to be John Chapell-48 but may not be. Mary's father was apparently supposed to be William Barker-3192, but his profile shows no daughter Mary. Mary has been detached from incorrect parents.
There is no record of her birth or her marriage. The 1611 marriage in Kent alleged to John Chapell was apparently to a John Upton.
Was Mary Barker a fiction created to supply a mother to immigrant ancestor Thomas Chappell?
