Looking for Bird Family from Melbourne

Siblings Elizabeth, Caroline and Edward emigrated from Henbury, Gloustershire England to Melbourne, Australia in1854.
Their other siblings Thomas, Mary Ann and George remained in Henbury. Their parents were John Bird, born circa 1792 in Westbury, Gloustershire and Catherine (née Handcock) born in Huntsfield, Somerset circa1792.

Elizabeth Bird married John Hogg in Melbourne in 1861. I've found no record they had any children.
Caroline had 7 children and died in 1868 in North Melbourne. She had 4 surviving children - Edward, George, Henry and Louisa. Louisa died soon after.

If anyone has any information on any of the mentioned Bird family, or descendants, I'd be grateful.
