The Marriage Entry for Joseph Ollier
All names are in bold for ease of reference.
Below is the marriage entry for Joseph Ollier (my Gt. Gt. Gt. Gt. Grandfarther) and Elizabeth Egerton, dated the 16th January 1797 as copied from the register of St Wilfred's Church, Davenham, Cheshire.

Both Joseph and Elizabeth signed with their mark, however both witnesses signed their name, the latter, Joseph Egerton, was almost certainly a relative to Elizabeth and may have been her farther.
