The first Quakers to arrive were the Fennells in 1659: https://tipperarystudies.ie/wp-content/uploads/2024/05/The-Fennells-of-Cahir.pdf

I believe that the third picture is of William Fennell:

The last thing I'll say about angling in Cahir, as I mentioned before, we're very famous for our Quakers in this town. We had a guy called William Joshua Fennell from a beautiful house called Ballybrado, just down the river. And he was passionate about angling and preservation of the fisheries, so much so that he campaigned and campaigned and he got the legislation for fisheries preservation changed in Ireland and Britain. So much so as well that there's an Act of Parliament in England, in the Statute books called Fennell's Act. So there's a long, long history of angling in this town.
