Peerage of England
The ranks of the English peerage are, in descending order, Duke, Marquess, Earl, Viscount, and Baron. While most newer English peerages descend only in the male line, many of the older ones (particularly older baronies) can descend through females. Under English inheritance law all daughters are co-heirs, so many older English peerage titles have fallen into abeyance between various female co-heirs.
Baron Byron
Baron Byron, of Rochdale in the County Palatine of Lancaster, is a title in the Peerage of England. It was created in 1643 by letters patent for John Byron, 1st Baron Byron, a Cavalier general and former Member of Parliament. The peerage was created with remainder to the heirs male of his body, failing, to his six brothers: Richard, William, Thomas, Robert, Gilbert, and Philip, and the heirs male of their bodies. Lord Byron died childless and was succeeded according to the special remainder by his next eldest brother Richard, the second Baron.
