I have found Australian royalty in the family - convicts transported from England in 1818. One is Mary Hitchen of Yorkshire, who married James Buckley from Lancashire.
There is lots of information on the internet about convict ancestors, Mary included. However, many family historians have repeated what I think is an error in her birthdate and place, and thus have listed incorrect parents.
I found that Mary was removed by the Overseers of the Poor on 14 June 1805 from Crompton in Lancashire and returned to her home town of Warley near Halifax in Yorkshire (while heavily pregnant).It is most likely, then, that Mary Hitchen is the one in the IGI who was born in Warley, not Halifax (she was actually born on 15 Jan 1786 and baptised 26 February 1786 in the Congregational or Independent Church of Warley). Her father is therefore most likely to be David Hitchen and her mother either Mary or Betty (more work needed here).Her parents are NOT Joseph Hitchen and Susan Sagar.
I am hoping to start a discussion with the aim of working out Mary's true parentage, and to find out more about her direct family.
