I hope this is posting is acceptable. I have the whereabouts of Roger Marshall's Headstone originally mounted inside a church 1892 which has since been sold as a private residence. The headstone has been removed and placed nearby in a safe place with a member of the clergy. It should ideally be in the hands of the Bell Marshall Family or Holloway family from Stroud Gloucestershire. Rogers son Mark Bell Bell-Marshall 1853-1914 married into the Holloway family wholesale clothiers and is buried in Stroud. This is a picture of the headstone. Please send me a PM if this post relates to you. Thank you
