I think I have cracked it; I have two lists and must have been looking at the Abrams instead of Abram. They family changed its name around the turn of the century to add the S, which does not help.
To make it even more interesting I received Walter's birth certificate yesterday to see that the registrar recorded him as Walter Abraham then crossed it out to change it to Abram. It all goes to show that we cannot trust 100% what we see when researching records.
Thanks for your time.
