Looking for Any Info on Jane Wright Married to Reg Cross Lived IN Berowra Nsw Around 1940s One of Eight Sisters Names Ruby Millie

HI

Dont have much info on my ancestors but my grand mother was Jane Wright, she married? Reg Cross, last known address Berowra waters nsw, Jane had as many as 8 sisters, but I do not know all their names, some moved to Cobar named Ruby and Millie. I know Jane had 5 children, Patricia, John , Jean(Babe), Alan(Bill) and Helen(Nell). Helen being my mother. I believe she died around 1950-1952. Reg remarried a cousin called Mollie Dwyer and Reg died about 7 years later. I know Bill still lives in Cobar, but alas I have no contact with him.. Can anyone help me with some info- My Mum does not recall much as she was adopted out to a distant Uncle in Maitland called Aubrey.
