I've also had some questions on this William.I believe the father is J. Daniel Herb.I've wondered if William, since he died during the Civil War, might have been in it?There was a Daniel K. Herb in Co K, 50th PA.If it's him, those records might help.
I have thatin Floyd's History of Northumberland, pg 567, it mentions Lewis K Yoder married Sarah Herb, d/o William and Catharine (Kehler) Herb.
Note that the 1860 census has a Susan Koehler, living with William's family.(a relative of the wife's?)
Still, I've seen the name Bolich also show up.I've wondered if maybe William was married twice, once to a Catharine Kehler (1833-1858?) and later to Catharine Bolich (1836-1878?).The latter would be the Catharine, buried at Zion Evangelical in Pitman.
There's a baptism at St. Pauls for a child of William, Catharine, in 1857, sponsors Johan and Katharine Wetzel
Sorry, I don't have the answer to this one, just more questions...
