TracySW on Family Tree Circles

I am looking for any information on my great grandmother Annie Marks b.1865 Carmarthenshire, Wales. I believe she died before 1911 as William was a widower in the 1911 census, but I can't be certain. I am not sure if Annie was a pet name or her actual name.
Annie married William Robert EMERY b.1862 in Cardiff (or maybe wasn't married at all as I think Wm was still married to a previous wife) They had 4 children, Reginald, Douglas, Gertrude (died before 1911) and Cecil. All born in Bristol. I don't know if Annie was the mother of four four.

I have tried to obtain birth and death records but my money keeps being refunded as no information can be found.

I remember hearing my grandfather Reg saying his father had been married a few times and there were about 13 kids. Wm married Lucy Lawrence in 1912
