Given names often turned into family names when people were identified by their father's name. For example, the first name Ahrend developed into the family name Ahrends by adding a genitive s-ending, as in Ahrend's son. Examples: Ahrends, Burkhard, Wulff, Friedrich, Benz.
crouching involves lowering the head and shoulders. Please explain in detail how one does this as you see it, including what is happening to the knees and hips. --Penbat (talk) 20:50, 14 July 2010 (UTC)
