Looking for Haestier – Spurgeon in Johannesburg South Africa

Thanks to a member of familytreecircles I have obtained some information, which just might help if there is someone out there looking for our branch of the family here in England

My search continues looking for any references to help piece together what happened to the branch of our Ryan family that moved to Johannesburg South Africa in the early 1900s

Searching for information on the following:

1 - Dora Elizabeth Mary Haestier born 1894 Brighton, Sussex, England
Children: = Denis Hayes born circa 1926 Johannesburg
= Blossom Hayes circa 1928-1930 but she died of dysentery

2 - John Prideaux Haestier born circa 1902 Johannesburg S. Africa (Jack)
1st wife – Children: = Charles Philip Haestier born circa 1930s
= Ian Robert Haestier born circa 1930s
2nd wife = Patricia Dorothea Haestier born 1949 in Johannesburg

3 - Thomas Frederick Haestier born circa 1905 Johannesburg S. Africa
(Fred) married Maria Susanna Meyer. Are there any children from this marriage?

4 - Francis Gilbert Spurgeon born circa 1913 Johannesburg S. Africa
Married - Rona Joyce Ireland born circa 1919in Pinetown, Natal S. Africa
Are there any children from this marriage?

Would be grateful for any information thank you
