Ernest was baptised in Sidmouth, Devon 22 December 1843:

There is no obvious reason why his birth should not be in civil registration, but I can't find it.
He is on the 1851 census in the Coast Guard Cottage with his mother and elder sisters in Rame, Cornwall, aged 7:

Then he disappears. He is mentioned in the will of his half-brother Osman Frederick Adams Edwards who died in India in 1865, but nothing else.
I assume that, like Osman and Charles his elder brothers, he joined the merchant navy but I can find no trace. Can anyone see him, anywhere?
