I have just read your Summary of James Border and Sophia Mason.
Sophia McClymont (nee Border ) who married Andrew McClymont(my ggrandfather)their marriage certificate indicates Sophia's usual place of residence was "Bangaroo" near Cowra,NSW and she died 22 Sept 1942 aged 95 at Homebush,Sydney,NSW and cremated at Rookwood Crematorium.
Andrew McClymont died 1 Jan 1898 aged 51 and buried at Cowra
Finally MULYAN,CARCOAR , BINALONG and WALLAROO are in the Cowra area
Otherwise your other info appears to be correct
