Well, that's how it goes, often:
"N. N. Klasdotter Djäkn is your 15th great grandmother."
"Märta Klasdotter Djäkn is your 15th great grandmother."
"Karin Klasdotter Djäkn is your 14th great grandmother."
"Anna Klasdotter Djäkn is your 14th great grandmother."
Via the Sursills:
"David Lynch is your 11th cousin twice removed."
