Merry, I have ancestors from Osmington too and we visited the village in the summer. They were contemporary with your Helliers. The surname was Charles and some of them in later generations were smugglers and associated with the Smuggler's Inn on the coast at Osmington Mills, where we had a very good meal.

If you scroll down the left-hand side it mentions the notorious Emmanuel Charles.
I expect our ancestors knew each other well!
