After the request for information an the "Ghosted" figure above, I was very pleased to receive the following reply from Linda Haynes in America....
Robert Beville and Joan Lawrence Beville, the couple on the left side of the monument, had two sons and seven daughters. One of the daughters, Susannah, was baptized at St. Michael's 28 Nov 1570, and she was buried at the church in May, 1571, so she was only six months old when she died. So probably she is the "ghosted" image, and the other six full size figures are her sisters. According to my book on the Bevilles, the record of her baptism and burial is in the parish register.
  Sincere thanks for your interest Linda.
