I need help in find Sarah's origins and parents etc.

At age 18 Sarah was arrested for stealing from Mary Smith's shop 14 yards of lace £3-13-6, 18 yards of lace edging £1-0-0, 3½ yards of muslin 7/-, 4 pairs stockings 7/-, 4 linen hankerchiefs 4/-, 1 printed shawl 8/-, 9 yards Irish linen cloth 16/6 and 1 muslin apron 6/-. She appeared at Hartfordshire Assizes on 3 March 1790, found guilty and sentenced to death by hanging. Since they needed women in the penal colony NSW she along with others had her sentence commuted to 'transportation beyond the seas" for the term of her natural life.
12 months later she left Plymouth aboard "Mary Anne" 300 tons in the "third fleet" on 16-2-1791 (11 ships and 200 convicts). They arrived Sydney Cove 9-July 1791. After 3 ½ years she married Thomas Hoskisson at St. Phillips Church Sydney by Rev. Richard Johnson the first Chaplin of the colony. Thomas could read and write and we think he changed his name from Hodgkis who was sentenced at Maidstone Kent and transported for 7 years. He was aboard "William Ann" part of the third fleet. They lived together for some time before being maried. They farmed along the hawkesbury river at Green hills (Windsor) and had 3 children. Sarah was pardoned by Govenor Hunter after recommendations from Rev. Richard johnston. In August 1799 Thomas and a friend was murdered by aboriginals whilst hunting in the lower Blue Mountains. These aboriginals were seen later carrying the blankets and firearms stolen. Two were caught and killed by other settlers who were charged with murder but local judges could not decide their fate and later they were freed form bail by English decision.
Sarah recieved compensation from Governor Hunter in the form of a land grant of 60 acres at Petersham Hill. Four years later she was married to Thomas Upton at Wi women in the penal colony NSW she along with others had her sentence commuted to 'transportation beyond the seas" for the term of her natural life.
