I have been unable to research John Dutton, the 1901 census has him living at 244 Liscard Road with his Grandfather and widowed father. I could not find any record of him on the 1911 census, the marriage has not been confirmed.
An interesting observation from Woods Wallasey Directory 1904-5. Three John Duttons as follows:
John Dutton Dairyman 101 Poulton Road.
John Dutton 6 Peartree Grove.
John Dutton Dairyman 244, Liscard Road.
On the 1911 Census Thomas Dutton Head of the family living at 244 Liscard Road. Records a total of nine children born alive with four having died.
On the family tree produced by Gary Dutton he records an additional two children William R.
Dutton & Albert E. Dutton.
