Your merge page tells me to merge duplicates but it lists Elder W'm Brewster and Mary ? as siblings of W'm Brewster's father and mother rather than separate generations and asks to merge duplicates. It will not allow to take them off the page altogether.
This is on the "parents of Jonathan Brewster page" .

By the way both my wife and I go back to Elder W'm. Me thru Patience and my wife thru Love.
