DR Harrington: Yes the Harringtons of Great Maplestead are direct descendents from Oswulf, although he is usually described as Osulph de Flemingby, not Haverington. Osulph was the earliest direct male line ancestor which Ian Grimble was able to identify when he wrote his history of the Harington (Harrington) family in 1957 and this detail appears all over the internet. However, since then there has been a lot of research done and I believe I can now demonstrate a firm link from Osulph going back a further eight generations to tenth century Northumbria. I will publish all my research when it is complete.
