Barbara Keller
Birth 1754
Shenandoah County, Virginia, USA
Barbara was one of the youngest of the children of George & Barbara (Hottel) Keller. She is named in her father's will; but I find no other record of her, so I'm hoping you can fill in the blanks. A family tree posted on Ancestry.com says she died 14 April 1823. I question that, as that was the death date of her brother Henry.
