Have you been to the Dingus cemetary in Wise County? There are several headstones there with names and dates, I am told.
Also there is a church that one of the Dingus relatives headed. William Dingus of Columbus, Ohio told me about it.
If I don't have the info, I am sure I have an e-mail address of a couple of people who would know who you are looking for.
My aunt kept all records, and went to every Dingus re-union at Twin Springs High School.

. He has a detailed chart, it is so thick he sent it to me by surface mail. Goes back to Philip and Jacob Dinges in 1773 in Dauphin County, PA.
