There's this wee thing called Wikipedia. :) Although, after all I've done for you, you still think she was a Ferdinand?! :p
There's a bit about their mother here: http://www.guardian.co.uk/football/2...obsmagspecial4
Describes her as "Anglo-Irish". When I saw Kane was being referred to as McGovern it pretty much confirmed my thinking on matters on that end. Anyway, I think that's enough on the Lavender, McGovern and Ferdinand families from me for one week!
