The 1840 Tithe apportionments list many plots as being “Cajel Trees”.
But what are Cajel Trees?
Pat Daffern thinks she has found out:
I think that the Cajel tree is the Blackthorn which bears Sloes as its
fruit. The wood is very, very, very strong and has long thorns. The
branches were used as CUDGELS and I think that is where the name
originates. In Ireland the sticks are called ‘Cudgel Shillelagh’ and
are still being produced today.
