Thankyou
I am trying also to track Frederick and Mauds daughter
May Louisa Marshall. Is it possible find her date of birth in approx 1901/1902
She marries William Alexander Jones in 1920. They have 3 children
She comes Mrs Brown when her father Frederick dies in 1941
She dies as Mrs Wilks and is buried in West Tce
She was also a Footall Coach to a senior team connected to the South Adelaide football club..
Cheran
I am not good with SA records and cannot see a marriage for May JONES and Mr BROWN.
However for your interest the divorce of May Louisa and William Alexander JONES in 1933.
https://trove.nla.gov.au/newspaper/article/74026010 And
https://trove.nla.gov.au/newspaper/article/132986711 Here May Louisa BROWN local football supporter and standing for council election in Grey Ward. 1949
https://trove.nla.gov.au/newspaper/article/130191379 And a lovely picture of her drying the dishes in her home!
https://trove.nla.gov.au/newspaper/article/130191437 She was as said, a supporter of local football and by 1942 Mrs Brown was team manager (rather than coach.)
https://trove.nla.gov.au/newspaper/article/54899280 Her address as 346 Angas Street Adelaide comes up on searches.
You will find details of the marriages of her daughters from the JONES marriage in 1946 and 1950. I prefer to leave that as they may be living people.
However in one of the marriage articles in 1946, May Louisa is identified as Mrs W A BROWN, that being her husband's initials.
There was a William Arthur BROWN living in Angas Street in 1951 and he was sued for the injuries to a cyclist.

EDIT- It is likely the right chap see next post.
