Thanks Len and Donna. I had ruled out Mark Charles Quayle because his grandfather was not John Quayle. The 1881 census has John Quayle 62, Elizabeth Quayle 61, Christian 18 and Mark Quayle 8 (John's Grandson).
The 1871 census lists other children Thomas 21, William 18, Edward 15 and George 14. William is my parental grandfather who married Jane Kermeen in 1892.
Mark doesn't appear on 1891 and 1901 census - at least connected with these family members. Any further thoughts?
