Alfred Kraushaar paid the deposit for Rosa to emigrate in November 1883. Mary died in January 1884. Rosa and Julie arrived in Sydney in July 1884. The girls would have left England about 4 months after Mary’s death.

Sukie Hunter says (2010):
James Downton Williams married Mary Bellamy Thorne in the first quarter of 1861 and on the night of the census they were at Barnsworthy, Dodington. They moved about a bit. Carey was born in Dodington and Rosa in Pitminster, James died in Pitminster in 1867 and the baby James Downton Williams (who was born in the same quarter that his father died, presumably just afterwards) died in Wellington RD at the end of the year. By 1871, Mary was the school teacher at West Buckland, which is just outside Wellington and may be where she went immediately James died. It is just a few miles west of Pitminster. She married Frederick David A. Cooper in Q2 1876 and by 1881 they were living in Highbridge, which is just inshore of Burnham-on-Sea between Bridgewater and Weston-Super-Mare. As well as Rosa (17, dressmaker, born Stogursey), they also had living with them Frederick's sons Frederick K. A. (17) and William H. (unclear - it might be 14 or 12), both born somewhere that looks like Burgwalls, Somerset, their mutual son Edmund T. (3, born Highbridge) and Mary's brother Joel Thorne (widower, 44, farmer, born West Quantoxhead) and his children Richard (8) and Sarah (6), both born in Devon. No wonder Rosa wanted to emigrate; they must have been very crowded.
