The name is properly spelled Brydges.
Here is the Wikipedia entry on the Barons of Chandos (no separate entry for the unremarkable William, who died in 1676):
For his brother the 6th Baron, we have:
"George Brydges, 6th Baron Chandos (1620-1655), was a supporter of Charles I of England during his struggle with Parliament, and distinguished himself at the first battle of Newbury in 1643.
"He had six daughters but no sons, and after the death of his brother William in 1676 the barony came to a kinsman, James, who was English ambassador to Constantinople from 1680 to 1685."
