Just to clarify, I have found out that Elizabeth's husband was Ernest George Williams, who died on 1st July 1942 of cancer, and NOT Ernest W G Williams.

Ernest & Elizabeth had three sons ~ Clive, Terry and Phillip.
After Ernest's death, Elizabeth had Royston David Williams in 1944.

After that, I believe she had two other children (Peter & Marilyn) by a Jugoslavian man (possibly Phillip), but they never married. Peter died in a motorcycle accident, and Marilyn died of cancer.

I would really like to know in which Church Elizabeth and Ernest married, and where they were buried.
