Rogers and Duncan families

[quantum1]

I'm searching for information (parents etc.) about Charles Rogers and his wife Esther Duncan (1806-1883). Esther died in Moneycass. She was a widow and her death record says she was a 'farmer'.
They had four children: George (married Mary Nixon), Henry, Catherine (married James Nixon) and James. Henry and James were born in Larah and Catherine was baptised in Kilnaleck in the parish of Kildrumferton. It records on the notes of her birth record 'peace police, pensioner and shoemaker and I assume it is referring to Charles)
Henry and James both migrated to Australia (James in 1866, no date for Henry).
