Looking for Decendants of James Southion Married Louisa Everett Hay Nsw Australia

I am looking for decendants of James and Louisa (Everett) SOUTHION. They had 3 daughters, Elizabeth born 1895 in Hay, Florence M born in 1896 in Balranald and Louisa A died in 1899 in Balranald.

I am also looking for decendants of Peter Voss and Bertha Radfer. It is believed that Bertha's mother may have been Johanna Fehlberg born in Prussia.
