hi rnzaf,
I can't say for sure if Hannah is the daughter of the same Robert Hilton, cant find a baptism for her, and as the Hiltons left England in 1854 for Australia I cant check the 1861 census for her either.
Found this researcher who seems to think they are one and the same

Would like to know where the name Woodrow comes from, sounds like a family name but have yet to find any connection to it...yet.
At this stage it seems Robert, baptised 12 oct 1817 Litlington,Sussex. Was the son of Richard Hilton and Barbara Wenham = 5 Dec 1803 Seaford, Sussex.
If these are his parents Richard Hilton must have died between 1817 and 1823 when barbara remarried to a George French 28 Dec 1823 Litlington
hope this helps. personal mail me if you want more details
All the best
