Henrike von Hanxleden - Henrike's mother?

Her father has an estimated birthdate between

Johann von Hanxleden zu Eisborn
Gender: Male
Birth: estimated between 1408 and 1468

So perhaps, his wife's birthdate is written as 1428 and death 1472, when perhaps it should read, like Johann's, 'between 1428 and 1472' and someone has mistaken the 1472 as date of death? If so, that would have made her about 27 when Henrike was born.
