I have over 100 Leydig's in my family tree but can't find a match to your Samuel or Edgar. It appears that many of the Leydig's married Kennell's but I can't find a match there either. I have other places I can look (census records) but will need approximate dates of birth and where they lived. I'm attending the Leydig reunion in PA on June 13. I also read that there's a Kennell reunion on the Sunday before Labor Day at the Geiger Church Pavilion in Somerset County, PA.
