Hi Liz,
Well ain't that something. I guess that you know that Tamworth is in NE NSW - I lived in nearby (but higher) Armidale for some years. As for Beechworth, Vic - my late father grew up in nearby Rutherglen; his father (active in founding Shearers' Unions - some say he founded the first SU) worked in gold mines there round 1900.
And yes, George B and Susannah were in Beechworth - they had a daughter there.
There are a couple more BRAS*INGTONs in Vic in the early times apart from Caroline Esther's marriage and little William's death.
BRASINGTON Charlotte, father Geo, mother Susanah DAVIS, b BEECHWORT 1855 #8979
BRASINGTON Charles Daniel (b London) m RICHARDSON Margaret Alma (b Sussex) 1882, #4970
There are also some BRAS*INGTON mothers (Mary, Sarah, Letitia, Harriet) to children named PERRY, RIDLEY, SCURRY and SPICER - are these relevant?
