There is a great story here that I'd like to learn more about:

In 1835 Luke Cullen was convicted of stealing by a court in Middlesex, England (near London), and sentenced to 7 years transportation to Van Diemen’s Land, which is now called the island of Tasmania, Australia.
He married Elizabeth Bunker and it looks like they had a large and successful family and many descendants. One of his direct male descendants submitted a DNA sample to the Sorenson Molecular Genealogy Foundation a year or more ago, and now has results available.
I would like to get in contact with anyone of this family or who knows the family.
