Hi Tas, I may have been in touch with you previously with the information that I have Coleman's in my ancestry and they are connected to the Cato family (my paternal grandmother) was a Maida Cato who married to Robert James Brown in Cygnet, Tasmania. I don't have an extensive Cato family tree in my possession but did get a print out of a family reunion which took place decades ago. Cheers Ainslie Pyne (nee Brown)
