The Arlington Hamiltons (Sean, Cristina, Frances and Grace) took the prize with Magdalene - after Mary Magdalene - Maggie for short. http://en.wikipedia.org/wiki/Mary_Magdalene. A name with an historical background, shortened to fit a cow AND a cute nickname. It had all of the important components and she even looks like a Maggie!
A Scottish surprise will be sent your way sometime in the future, hopefully before the end of the year.
Great job everyone and thanks for the suggestions. Maggie will be so pleased with her name.
