Harrington was twice wed, firstly to Isabel English (by September 1369), His second marriage brought him an augmentation of his estates, as Joan was a
widow, and controlled her dead husband's estates in
Huyton and
Knowsley. There was no issue from his second marriage. Harrington appears to have died sometime before February 1404, after which he leaves no official trace. His estates passed to his eldest son, Sir William, and Nicholas and James entered the household of
Henry IV as
squires. Sir William became a
Knight of the Garter displaying the arms
Sable a fret argent, while Sir James combined the
tinctures of his paternal arms (sable and argent) with the arms of Henry IV to create differenced arms, blazoned:
Sable three leopards argent. Via his daughter Isabel, he is the great-great-great-grandfather of Queen
Katherine Parr and great-great-grandfather to
Bishop of Durham Cuthbert Tunstall. Via his daughter Elizabeth he is the great-grandfather of
Thomas Stanley, 1st Earl of Derby (husband of
Lady Margaret Beaufort and step-father to
Henry VII of England). ==References==
