John Brien and John Dawson Brien of Castletown Monea:
Frank, I'm sorry to say I have no more information about them, except
that I think one of them served as Sheriff for a while and was often
on the jury for the assize trials --I'd have to look it up, but
roughly 1820s through 30s (and probably beyond that, but that's all I
had the newspapers for.)
If I remember correctly they were married in Dublin, but probably
that is where Charlotte Dawson was from.
If you find out more, I'd love to know more myself.
