Looking for descendents of Rev. Richard Johnson, first fleet Australia
The Reverend Richard Johnson arrived in Australia on the first fleet in 1788. (b. 1755 in Yorkshire; d. 1827 England)
Married in England on 4 Dec 1786 to Mary Burton (b. Abt 1753 parish of St Poultry, London; d. 1831 England)
Had three children
1. stillborn Oct 1788 Australia
2. Milbah Johnson (b. 1790 NSW, Australia; d. 1803 England)
3. Henry Martin Johnson (b. 1792 NSW) returned to England with family in 1800; married Hannah Bartram 1815.
Who were Henry and Hannah's children? Any help much appreciated.
UPDATE: 25 November 2009 - Henry and Hannah had no known issue. Claims that William Jonathan Johnson is a descendant of the Reverend Richard Johnson are unjustified. The Rev. Johnson may however, be a great uncle to William Jonathan Johnson, as his brother, Robert Ebenezer Johnson lived with his great aunt, who (according to information provided by Ruth Fielding), was Rev. Johnson's sister.
