Hammock Use In The 18th Century.

I received a request for information on the use of hammocks on land in the 18th century. Whilst I have as yet not been able to find any primary documentation on the use of hammocks for camping, I have found some images.
When you want to use a particular item in 18th century living history, you must first establish its existence and availability. IF you find that it is possible that your persona could have come in contact with such an item, then you may have a precedent for using that item. For instance, in the case of the hammock, were you once a seaman? Did you travel on a ship & use a hammock? Where else might you have seen a hammock in use?
