There is a comment on a tree on Ancestry to the effect that:
John Bridgart, b 1787 Derby, d 3 June 1868 Adelaide, Australia
m Ann Walters, bap 1810, Belper
possibly 1 May 1845, at Gretna?
No sources mentioned, except the comment mentions an email from another Ancestry user.
The 1861 census simply doesn't show a father! Neither does the 1851 census?!
Just means that he wasn't at home on the nighth of the census.
