NickiFry on Family Tree Circles

I am looking to trace some distant relatives who live in the Newcastle area of NSW.

My Grandmother's sister (on my father's side) emigrated to Australia around 1920. She met and married an English man by the name of Frank LEDBURY. The details are as follows:

Sarah HODCROFT (b. 1892, d. 1971) Married Frank LEDBURY (b. 1899, d. 1963) in St Pauls Church, Stockton, Newcastle on 3 June 1922.

They had 5 children:
Edgar Hodcroft Ledbury (b. 1923, d. 1964)
Frank Maxwell Ledbury (b. 1924, d. 2002)
Mary Francis Ledbury (b. 1927) ..... Possibly married a David CRAWFORD in 1949
Deveda Jean Ledbury (b. 1928)......Possibly married a Pactrick O'BRIEN in 1947
Beverly D Ledbury (b. 1935) .......Possibly married a William James GRICE in 1955

My Father (Frank BOWN) use to write to Deveda & Mary either just before WW2 or just after but lost contact. The last address that we have for the family home is:

29 Maitland Street, Stockton, Newcastle, NSW

We thought we had found Deveda using the White Pages and sent her a letter but we have had nothing back sadly.

If anyone can help with finding any descendants that would be most helpful.

Thanks
Nicki
