Find Ancestors

I have a Sidney G Arnold 1907 and a John Sidney Arnold 1909 both children of John Walter Arnold and Louisa Jane Arnold (nee Rondeau). On 1911 Census it states one child living and one dead. I have found both births but cannot find a death. I am guessing that the 1907 one is the one that died and the second born 1909 was named after the deceased.
Can anyone find a death please, I have searched Ancestry and FreeBMD without success.
Thank you for any help.

Andy

As far as I am aware there wasn't a daughter Jax.

Andrew if Sidney G Arnold was born after the 1911 census he must have been the 3rd child as the Census Record shows two one dead and one still living, but I can't find a death registration of the first Sidney G Arnold.

I can't see an earlier birth for a Sidney/Sydney G Arnold ihe correct area.

Andy

Do you have the birth certs?

I cannot see a Sidney G born in 1907 either

Sorry, it has just registered what you are thinking, I'm a bit slow with this!!

I need to go and check out the 1907 birth and ? whether girl or boy.

Thank you for your help.
