Was this William Finley a founder of the Tinkling Springs Church?

A William Finley is listed as one of the founders of the Tinkling Springs Presbyterian Church in 1744. See http://familypedia.wikia.com/wiki/Tinkling_Springs_Presbyterian_Church.

I've wondered for some time if William Finley (1712-1789) was the William Finley listed among the founders.

The Glasgow Family History, p. 31 says "The Finley's first settled at Oxford, Pa., then Wm. and son Robt. went to Staunton, Va. to Tinkling Springs congregation...."

IF that is correct then our William is NOT the William Finley listed as one of the founders because Robert wasn't born until 1745.
