I am perplexed and confused AGAIN!!! I need help to confirm a marriage between William C. Wertz b. 1814 and Elizabeth Boor or Elizabeth Gibson...here is my problem:

I have a record from Bedford County Biographies, Containing Life Sketches of Leading Citizens of Bedford and Somerset Co., PA, Boston. Biograhical Review Pub. Co., 1899 pps 227, 228; for William C. Wertz s/o John and Elizabeth (Williams) Wertz b. April 14, 1814 which clearly shows that William C. Wertz married Elizabeth Boor - as follows:

"On November, 3, 1839, Mr. Wertz married Elizabeth Boor, a daughter of Michael Boor, the descendant of a pioneer settler of Cumberland Valley Township. They have reared six children, as follows: Mary J., wife of John A. Beegle: Melvina: Scott A.,: Amanda E., wife of M. B. Smith; Ann C., wife of W.S. Oster; Rachel E., Scott A. Wertz, the only son, was born July 6, 1845, on the home farm, which he is now conducting in a thorough and skillful manner, employing the most approved modern methods and machinery. Nor is this all; he gives a part of his interest to the cultivation of about thirty-eight acres of his own. Energetic, practical, and possessing much business ability, he takes a deep interest in matters pertaining to the welfare of town, which he has served one term as Assessor. He is an active member of the Lutheran Church, of which he has been the treasurer and is at the present time a Deacon. Of his union with Rachel Smith, late of Bedford County, Pennsylvania, one son has been born; namely, William W. Wertz."

My problem is that I am finding Family Trees on ancestry.com that are showing William C. Wertz with the same birth date and the same parents having married an Elizabeth Gibson...

Can anyone help to clear up the problem for me??? Any and all help appreciated!!!
