Hi Stephanie,
We could very well be cousins, I have heard that there are many variations of the name Yelder. In my search of my family I have seen on some census the spelling of Yeldell, so I use both when looking. On my Fathers birth certificate his Mother spells it Yelder. Her name was Mary Lou, she had two sisters Emma, and Zettie, there may be more siblings, but I haven't been able to confirm that at this point. If any of these names are familiar, please don't hesitate to contact me as I have some information in my branch of this family that may be helpful to you. Who knows it could lead to something more.
Be Blessed
