Many of you know about the Looney DNA Project already. You are probably
aware that the results to date indicate that a significant group of
descendants of Robert Looney (c1692-1770) who have been DNA tested are from
Haplogroup I1, usually considered a haplogroup from northern Germany and
especially Scandinavia. This fact, along with the history of Norse Viking
settlement of the northeastern portion of the Isle of Man where the Looneys
live, point strongly toward a Viking origin for the earliest male whose
descendants later took the surname Looney. Now a study is underway from an
English university to determine the degree of Viking ancestry on the Isle of
Man. Looney, and Lewney are 2 of the specific surnames chosen for DNA
testing from a list of surnames present on the Isle of Man in medieval
times. Here is the link:
