My Evans family line is somewhat short, only tracing back to 1850 and my Great-Great-Great Grandfather. Here's the line:
1. Sally Ruth Evans [Great-Grandmother]
--- born: 17 Aug 1902, Hart County, Georgia
--- died: 20 Jun 1999, Hartwell, Hart County, Georgia
--- married: Bennie E Craft, abt 1918
2. John H Evans [Great-Great Grandfather]
--- born: 28 May 1879, Elbert County, Georgia
--- died: 9 Jul 1911, Gaines, Elbert, Georgia
--- married: Leila Frances Craft, abt 1897
3. William A Evans [Great-Great-Great Grandfather]
--- born: 18 Sep 1850, Hart County, Georgia
--- died: 2 Oct 1917, Ira, Anderson, South Carolina
--- married: Harriett Ann Partain, abt 1872
4. Unknown Evans
--- born: ?
--- died: bef 1860
--- married: Bedie / Beady
Having written that out, I see that not only does this line go back very far, but it has been elusive regarding marriage licenses!
The initial problem with this line is that I can't find the family in the 1850 census. William's parents should have been married, perhaps just starting out together. I also haven't found a marriage record for a Mr Evans to a Bedie / Beady in Georgia. It's likely they were both from South Carolina, which doesn't have as many available records. I don't see this line a brick wall, so much as a temporary road block. I need to spend (a lot of) time going through records to find GGGG Grandpa Evans. I'm sure there's some record of him somewhere. There are a few online trees, that do not give sources, that say he was Powell Evans from Cherokee County, South Carolina. But without sources, I have no idea where this idea comes from and have yet to come across any substantiating evidence myself.
