Caroline Dunkelberger Vansickle - IN

Alice Vansickle, b. 1856, married Morris Bowling in Fountain Co. IN.She died there in 1938.Her death record lists her parents as Samuel Vansickle and Caroline DUNKELBERGER.
I find a William DUNKELBERGER in 1850 Fountain Co. IN census.Was he father of Caroline?Assume that was her first, not middle name.
Were there other DUNKELBERGERS in Fountain Co. IN in that time 1850 to 1880?
Possibly her parents were from a nearby IN county or OH ?.
