The 26th of January is Australia Day so several geneabloggers wrote posts about the day.
Anne Young’s post, Climbing our family’s gum tree again, referred to a C’mon Aussie Australia Day Challenge Pauleen Cass had issued in 2014 in which Pauleen had used the term Gum Tree.
From reading these and other posts in the challenge I would suggest that a Gum Tree is a family tree that lists our ancestors and family members who were born, lived or died in Australia.
