my father always thought our last name was a variation on shortlegs
because everyone in the family had short legs 'kratoska' krat similar to latin=crutus or english curt. so he traced the ancestry back to 1585 (took several years to do this) and found that an ancestor bought a farm and took on the name of the people that live on the land. so our name actually was something else (like digger or miner)
which he didnt like at all.

oddly enough the family eventually lost the land about 1850 but when my dad visited the farm and talked to the lady who lived there they had an interesting chat - and when he left he thanked her, and she said 'oh but my name is not Kratoska, thats what they call me because we live here.' our name is something else.
