Hi
This is a difficult one. Regarding your friend and you don't put info on the site of still living people.
How old was Lily when she died and when and where was she born?
Are you trying to find Lilly parents and siblings? Did Lily and her husband have any children?
Does your friend have her birth certificate?Where in Cardiff in 1935 was she born?
Is this lilys marriage
