hi Sylvia, Sorry it has taken me so long for me to answer your email, I had a look at my data for the PLUMMERS 1st William was b. 29/5/1829 Richmond, NSW to George Plummer & Sarah Griffiths... he m. Minnia Brown their son also William, middle name James was b.1852 Richmond, Tas. and M. mary jane Temple 8/7/1878 Richmond, Tas. So as you can see I do not think we have a connection. Plummer was also speltPLOMER have you looked in www.records.nsw.gov.au in their colony secretary indexs?
