Birth: 1775 Dorking, Surrey, UK

Mother: Mary Buckman b1756-a1786
Christening of Ann Croucher in the IGI on 23 June 1775 in Dorking parents Thomas and Mary Croucher and her death on 2 March 1787. However there is also an entry for Hannah Croucher, same parents, same date for death, but different christening date (1 November 1783). The entry in West Surrey Family History Society West Surrey Burials is for Hannah, not Ann.
Lynda Jones/Elson has an entry in RootsWeb WorldConnect for Ann Croucher christened on 23 June 1775, parents Thomas Croucher and Mary Buckman.
Lynda Jones also has an entry in Ancestry Public Member Trees for christened on 23 June 1775, parents Thomas Croucher and Mary Buckland. Another entry adds her death on 17 April 1777, but I cannot find any confirmation of this date which is also given for Elizabeth and Sarah.
