I too am descended from the Montgomery County Breys. I discovered it on my 4th great-grandmothers Philadelphia death Cert. It says her parents were Martin and Martha Bry and that she was born in Montgomery County. She married James Haddon about 1830. Her father was the son of Christopher Brey, who was the son of the first Brey in the country - I think his name was George Bry and he came to this country in 1737. Chris Brey served in the Revolution. I found it on the 1840 census.
