My money is on the 1936 death
1937 Amos John is at the same address on the electoral register with an Eliza Elizabeth Taylor. There's a marriage between an Amos T Taylor and Eliza E Mitchell in Horsham, Q2 1937, which matches a tree on Ancestry and pictures of the address
There again, this all needs to be checked more carefully - Amos is a fair deal younger than Mary Ann, so we could have different generations with the same name here
