Hello, well it is 8 years later now being 2014. Perhaps you now have the information you need but I will let you know my own info anyway. The James Easton you are talking about who arrived on the Blenheim appears to have been a convict & could not have been the father of Frederick Charles Easton.

FC's father was James Easton, shoemaker, who arrived at Port Phillip (Victoria) in 1841 per Sir Charles Forbes. He was an assisted immigrant (not a convict) from London and arrived with his wife Mary 32, daughter Elizabeth 8, and son FC aged 1. The family then sailed to Launceston where they lived for several years then moved to Melbourne. This James is my GGG grandfather. I believe he died in 1888 in Melbourne.

My information comes from a genealogist I consulted about 30 years ago as well as my own researches 14 years ago when I visited Hobart. Although my Easton's arrived free they married into convict families - so I have my own skeletons in the closet (lol).

Kind regards,
Claire Easton.
