Corina kindly sent me some links to references to tatting in some ladies' letters in the 1810's. I've done a cut and paste of part of the pages.
Joanna Baillie was a poet and playwright born in Scotland. Mary Cumming was an Irishwoman who had emigrated to Virginia.
Joanna had been given a length of tatting and asks her friend if she knows what tatting is. Mary had just learned to tat and is describing how to do it as though her friend would not know how. (Even then, as now, the beginner's difficulty in getting rings to close is noted as the hard part.)
I can envision this as a time when the art of tatting was just starting to spread from person to person in the English speaking countries, while we know some decades were to pass before there would be published instructions.
I'm sorry the print on the clips is so small. Here are links for closer looks at these pages:
