Edgar, thank you for the Cook/Harwood information. I am an American descendant of William Harwood from the 18th century village of Littleport, Cambridgeshire,England. I have done the ydna testing by Family Tree and discovered several seemingly unrelated close connections to the Cook surname here in the US. So far I have been unable to trace these Cook families to exact English locations. The Cook connection seems to be about 4 to 5 generations ago when all of my Harwood ancestors (so far as I know) were still in England. I'm thinking that maybe a female Cook had a male child fathered by a Harwood but kept the Cook surname?! Pure speculation I know but that is one explanation.
