There is definitely a connection to the Brady family since the Mulvaney farm at Edenburt/Whitegate Cross passed to the Bradys by marriage. As for the O'Reillys, my great great granmother, married to Luke Mulvaney, was Judith/Julia O'Reilly.

I also have a Mary Brown connected to the Carolan family, but the relation is only by marriage. However, this Mary is connected to my Carolan and Fitzsimmons relatives.
