Hi I saw you was online and took a chance you'd read the reply

I saw the birth and death and wondered if that had something to do with Amelia being missing from the 1891 census. Charles states married but is with his parents and Lilian.
A tree on Ancestry has Amelia dying in 1944 but that's another one and she was married to a Frederick.
It maybe that they lost their son and Amelia couldn't cope with that. She may well be in a hospital under care and could be listed just by A.B or even A.D I have tried allsorts. So today I decided to have another crack as its raining here! I will keep at it and see what I can find.
The fact that Charles and Alfraetta marry in 1925 may give us a date but it may tie in to her death the following year if she was ill.
Thanks for getting back to me I'll let you know if I find any more.
