Morning Joan

There is a tree on Ancestry with John's parents as Robert and Sarah
is it your's ?

Hello everyone I hope soo much that you can help me.
I am tracing the paternal side of my family tree I have come to a standstill. My GG Father John Thomas Rogers was born in 1854 in Woolwich, England. I have most of the information about his marriage, children etc, however when I try to go back further I hit brick walls.
I know his father's name was Robert. It was on John's marriage certificate and also in 1871 England Census : Robert is listed as 44, a Laborer and lives with his wife Sarah and children John, Sarah, Rachell and Edward at 5 B?????? Buildings Woolwich Dockyard, Woolwich.
In this census Robert is listed as being born in Newcastle on Tyne.
I also know that around 1854-1857 the family sailed to Australia as Sarah b1857, Rachell b1858 and Edward's b1863 birth records are there. There were also two other children Ann b 1860 and Robert b1862 born in Australia. I do not know what happened to Ann or Robert as they do not appear in 1871 England Census. Obviously the family sailed back to England after Edward's birth in 1863. The reason for going to Australia in the first place is unknown to me.
Any information you could give me would be HUGELY appreciated.
Regards
Joan
