John William Haddon would be the dead one of her 5 kids I guess. Who was George Henry Haddon's mother? (I can't get on the GRO website at the moment, they're having problems with their emails).
Also does it tell you about marriages? My best guess is
Joseph Henry Osborn/e, was born 1873, Hull, married Emma 1895, but I don't know her surname? I think she died in 1910.
Have you found the OSBORNEs in 1911? I haven't had any luck Find them and James is probably still with them.

You're both very kind in doing some research for me. I spent a few hours trying to find the 1911 census for Joseph H Osborne and I nearly lost the will to live, and it's my family!
One thing I've noticed is that censuses that turn up in Ancestry search don't show on Family Search, is that a known flaw? And the same for disparities between BMD and GRO searches. Which is strange, as don't they both use the same sources? For example George Henry & John William Haddon don't show up at all on BMD. Is it common for people not to show up on record data bases generally? Because of misspelling or just lost or whatever?
Also, do you know why BMD doesn't use mothers' names from pre-1911? I always assumed it was because they weren't in the records, but you've shown not to be true, so does anyone know why they chose not to digitise them? It seems bizarre. Does that mean that a lot of researchers don't really bother with BMD anymore?
Also I've only just twigged that the live birth column in the census is just for that marriage and not for all your children, another source of my confusion. So there are three kids missing from J.H.Haddon's second marriage (or one, if like me, they didn't understand the form).
