Hi, Tim,

EATON, Henrietta; WORTHINGTON William; Walton, St. Mary; Liverpool 2012WD/23/59
This is the only Henrietta EATON marrying about 1920 in Liverpool that I found. I think that St Mary, Walton, is the Parish Church for Walton-on-the-Hill, (Anglican).
I also looked for Alice, but there were several so a bit difficult. There is one Alice C. that MIGHT be the one you seek. It is a Register Office or Registrar Attended marriage so the only way of getting further information will be to buy the certificate.

If it was a Registrar Attended marriage it is likely that at this date it was a marriage in an RC church. There is an on-line index of RC marriages in Liverpool (
http://www.liverpoolhistoryprojects.co.uk/liverpoolrcmarriages/ ), but it only goes to 1901.
Hope this helps
