What is the time frame that you are looking at for William Brady. My grandfather was William Wells Brady. His father was William Edward Brady. Their line goes back to Lindsey Anderson Brady, who was a pioneer to Utah, and then further back to a Hugh Brady, who came from Ireland about 1732 to Cumberland Co. Pennsylvania. I have a book that starts with Hugh Brady and contains all kinds of records relating to the Brady family clear up to about 1938.
Sample from the book:
"Of the original 7 sons of Hugh Brady only two, Joseph and Hugh II, are thought to have died in Cumberland County. Three others, Samuel, Ebenezer and James moved to Indiana County and died there. Captain John Brady, as is well known, is buried at Muncy, Lycoming County, and William the remaining son is said to have migrated to Tennessee."
