I think they must have been related in some convoluted way
Robert Dudley 1st Earl of Leicester (1532-1588) was the son of John Dudley Ist Duke of Northumberland (1502-1553)
Edward Dudley 5th Baron Dudley (1567-1643) was the son of Edward Sutton 4th Baron Dudley (1525-1586); and Edward was the son of John Sutton 3rd Baron Dudley.
John Sutton was called Lord Quondam meaning Lord Has-been or Lord Formerly because he allowed his cousin to take over his lands, including Dudley Castle. His cousin was John Dudley, Duke of Northumberland. After northumberland was executed because of the Lady Jane Grey episode Dudley Casstle returned to the Crown and in 1555 Edward sutton 4th Baron got it back and was reinstated.
John Sutton 3rd Baron Dudley seems to have been 3rd cousin of John Dudley 1st Duke of Northumberland so I make it that Robert Dudley Earl of Leicester and Robert Sutton of Netherton Hall were 4th cousins twice removed
But I may have worked it out wrong and it is confusing that the name Sutton and Dudley are both used!
