Hi, Tati,
That was quick! My data is on another computer at the moment, so I'm relying on memory.
Their son Samuel was born around 1846ish, and Elizabeth was born a couple of years later. The kids appear on the 1851 census as living with their grandfather James Cottage. Samuel came out to Australia when he was 18, and Elizabeth came in 1896 as a widow, with her 5 children. (She married Amos Swan)
Regards,
Kerryn
