Searching for the Cumes line outside of Chewton Victoria

Hi everyone,
The Chewton side of the family tree are hard at work trying to find any link to CUMES ancestors.

My great great grandmother Louisa got married under the name SALTER to her husband Patrick CLARKE.

Now Louisa Salter was not her birth name.  Louisa CUMMIS was her birth name.  I have written in another blog about the many many ways their name has been spelt in various documents.

All of Louisa's brothers and sisters changed their birth names from Cummis to either Salter or Armstrong.  Louisa's mother's birth name was Elizabeth ARMSTRONG, but she used her stepfather's surname SALTER until the day she died, even after she married.

Today I searched Cummis again in Ancestry and found something different. I found a death record for one Laura Elizabeth Cumes who died in 1962 in Castlemaine, Casterton.  Chewton is practically a suburb of Castlemaine.  Laura's birth surname was Cahill.

To the marriage records I go.  I found Laura Elizabeth Cahill marrying one Albert Bede CUMES in Marrickville, NSW in 1944.

Off to find Albert's birth records.  Albert B Cumes was born in 1885 to Henry and Mary Ann in Moruya NSW.  Albert B is also listed as the father of Albert R Cumes born 1910 in Moruya NSW.  Mother for Albert R is listed as Helena W.

So back to marriage records for Albert B looking for wedding with Helena W. I find him marrying her in 1909 in Sydney. Her name is listed as Helena Latta, but close enough to keep working I figure.

So to see if I can get this potential ancestor sorted in my head and stop my eyes rolling around counter clockwise.

1. Henry Cumes and Mary Ann gave birth to Albert Bede Cumes in 1885 in Moruya NSW.
2. Albert Bede Cumes married Helena Latta aka Helena W in 1909 in Sydney NSW.
3. Helena gave birth to their son Albert R. Cumes in 1910 in Moruya NSW.
4. Did Helena die?
5. Albert Bede Cumes remarried to Laura Elizabeth Cahill in 1944 in Marrickville NSW.
6. Laura Elizabeth Cumes nee Cahill dies in Castlemaine, Casterton.

Ok so follow my logic.
a. Gotta find Helena's death certificate or a divorce.
b. Where and when did Albert Bede Cumes die?
c. Why did Laura Elizabeth Cumes nee Cahill move from NSW to Castlemaine, VIC?

All this work and we don't even know if the families are related.
Historically yours,
