Does your record of the Penryn Cemetery on the birth of Samuel R(K)Bentz read Oct. 30, 1843? If so I may have a new lead for you. Emmanuel Bentz,(son of William, son of Peter, son of Weyrich) was born abt 1813 and moved to Lebanon and had the following children: Adam (abt 1836), Samuel (about 1842, Susan (abt 1846) and Charles (abt 1849) While the cesnsus for your ancestor Samuel shows his birth as Abt 1846) it could be in error. given the date on the tomstone. Hope it helps. Regards, Ed.
