Hi Chelsea, 1913 marriage is in Cheshire BMD, they married at St Mary's Birkenhead. If you look in the births you will find about 6 children born to them.
You may have to send for the marriage certificate for 1943 marriage. You could look in the 1939 register for the first couple at FMP. Have you Lily's family in 1911, she was 27 with her parents a domestic servant. Too many Robert Murphy's and with no age or birthplace, makes it difficult. Again 1939 may reveal something for you.
