Ed Smith,
I am the granddaughter of Francis Christian Jahn. My mother was his youngest child (Maggie Bird). Her mother (Margaret Missouri Goodwin died when mother was just 3 weeks old. He then married Sophronia Curry Matherson.

Grandfather was a doctor and did practice medicine in Waller County, Texas.
Aunt Eula died in Dec. of 1968. In Tarrant Co. Tx.

I agree that William Christian Jahn could very well be a descendant.
