Jeremy:
Welcome to Ireland Reaching Out!
I think your Brides came from one of two civil parishesin Co. Cork: Castlemagner or Kilroe which border each other. I lean towards Castlemagner. Below are two links which contain the 1852 Griffiths Valuation head of household listings for both parishes. You will note two Henry Brides in Castlemagner and one in Kilroe. (It is possible that in Castlemagner, one Henry Bride was leasing land in two townlands).
Presuming your family was RC, I searched on Roots Ireland. I did not find William but did locate two likely siblings in Castlemagner RC parish records-- Ellen and Robert. Below is the parish register for Castlemagner. You may want to search for other baptismal records.
Let me know if you have questions.
