catkins on Family Tree Circles

I am trying to find out more about the back ground of my 3xgreat grandfather William Wood.bt 05.04.1801 Sandhurst Kent. It appears his father was also William Wood and mother was Elizabeth Igglesden But I cannot find anything else about his parents or if he had siblings. I do know that he moved to Sussex, and married a Elizabeth ?Fuller alias Rolles in Battle.27.01.1823. She was of that parish yet on the census's she is stated as born Gibralta, British subject. But if she is the daughter of the Fuller family that I think she is they never went abroad as far as I can see, not even in the Military.
So who are my 2 Elizabeth's 1795c and 1801c, and William 1795c ???
