I agree with you Lee and shume.
Also, even though it is not a sound research pathway,

I do note that one of his daughters with Bridget was named Jane.
GREENLAND Jane
8117/1865
James & Bridget
At DENILIQUIN
We may take this as a tribute to his mother Jane as shown on earlier Wiltshire Records and matches with the mother's name on his DC. The surname ROCHARD is a bit of a puzzle, however.
Twenty years between his marriages is interesting.
Where was he ?
Where was Ruth?
