Ewing/Hindeman or Hindman - PA

I am seeking information on William H. or W. Ewing (b. 1828), who married a Ms. Hindeman in Indiana Co., PA. Her first name is unknown.

William Ewing's parents were John M. Ewing and Lettice Work.

I have noted that the HINDMAN family lived in Westmoreland Co. and surrounding areas at this time, and our family records showing "Hindeman" may be wrong. If you have any information along this line, I would appreciate hearing from you.
