I am looking for information on the mother of Charles Monroe Hetrick of East Butler, PA. Census Data confirms that he was the son of Edward Hetrick. Edward was apparently married twice (once to a Sarah Dinger, and again to an Elizabeth Hinderliter). Some liberal math would make Elizabeth Charles' mother, but Charles' death certificate lists his mother as "unknown." If anyone could confirm Charles' mother to be Elizabeth Hinderliter (or some unknown person) it would be greatly appreciated. According to the relative that I e-mailed a few years ago, Elizabeth Hinderliter was Charles' mother, but I do not know the source, and have unfortunately lost the relative's e-mail address. The death was reported to Butler County by Charles' son, Charles L. Hetrick. Charles M.'s living son apparently has no knowledge of a previous marriage by his grandfather.
