Hi Trish & Sue, just got back from helping my husband who is renovating a worker's cottage. Gave me the worst job, de-nailing all the tongue & groove boards

, who wants to be a renovator , back is aching, finger nails cracked, anyway enough of my woes
Sorry ladies I know very little of the family background. Like you I couldnt find anything on Free BMD or Family Search. I was told their names by the lady I am assisting. I also found their details on Queensland Archives site for assisted immigrant passenger 1848 and May 1884. The family came from London on the "Royal Dane" arriving Rockhampton 19/11/1870 and then onto Brisbane.

Sue you could be right, perhaps they had to tie the knot, before being accepted as assisted immigrants by the Queensland Government. Their vessel departed Gravesend London on 30th July, 1870.
Your 1861 census Trish is interesting, the ages all fit in.
Bye for now
Helen
